I don't know how many packages that is but it's WAY over the minimum of 5
advised in the dev handbook

No, libvpx is what's used to produce webp/webm things, afaict. So in the
case of php, that flag should probably be renamed.

Half and half. The "suppoprt" is obviously a typo, but unfortunately,
PHP uses a bundled copy of GD, so that isn't.

...and there's more. In php-7.x, they've dropped libvpx in favor of
libwebp. Our existing USE=vpx (to pull in libvpx) therefore does nothing
in php-7.x, so I'm going to change it to USE=webp and have it pull in
libwebp instead. It takes forever to compile-test, but I'll push a fix
afterwards. Thanks for noticing!

The existing use description might be considered slightly confusing,
potentially ..

I changed them to,

  <flag name="vpx">Enable webp support for GD in php-5.x</flag>
  <flag name="webp">Enable webp support for GD in php-7.x</flag>

Ok so this is really OCD I know .. but might be worth adding the libs, e.g.

<flag name="vpx">Enable webp support for GD in php-5.x via libvpx</flag>
<flag name="webp">Enable webp support for GD in php-7.x via libwebp</flag>
[[not checked for syntax]]

for example, but what do I know ... [ie. links the flag to the lib]

would a REQUIRED_USE in newer versions make sense to force the new use
flag for people upgrading as a deprecation period?

Alternatively, you likely want to look into restrict attribute to flag tag

What's the migration path/timeline look like .. I'da thought it would be
months/years to move everything that's centred on php5 up to php7 if
that's the way things are going. What happened to php6 ?!?

Personally I'da thought an ewarning would be sufficient based on the old
flag, and perhaps a news item if considered important enough?!

You mean like requiring USE=webp (new) if the user has USE=vpx (old)?
Sounds like a good idea. It's been totally broken for months and nobody
has noticed, though, so I'll probably wait until the next revision.

as long as it is sufficient time and it notifies ahead of time, and the
new use flag can be added to package.use immediately, indeed, although I
believe an elog is more appropriate than ewarn in that case.

v5 and v7 are mostly compatible, and the few big changes have had
deprecation warnings for years.

What happened to 6: you know how some elevators don't have a 13th floor?

I vaguely remember that this can be done automatically, through 
config_protect to create/update a package.use entry.

Don't ask me on any details though. ;)

LOL - that still happens?!

I still see php5 installed as stable everywhere .. so perhaps php7 still
has a little way to go (not that I would be *so* stupid to suggest that
something like 'debian' was a barometer of such things, nooo..!!!)

Yeah, at least in the U.S. There was a "PHP 6", but everything went so
wrong that they decided to just pretend that the number 6 doesn't exist.

We've still got 5.x stable, but that's because there's a security bug
for PHP every 20 days and it takes 30 days to stabilize an ebuild.

Here's a status report:

  * We've got the "eselect php..." stuff sorted out already so you can
    easily switch between 5.6 and 7.0 on-the-fly.

  * Most extensions have a version that works with php-7.0.

  * Some PECL extensions only work with certain versions of PHP, yet are
    not slotted. This will probably cause some headaches, but it's
    pretty late in the game and I don't have the time to overhaul the
    way we do extensions at the last minute. We may have to tell people
    that they can't switch between php-5 and php-7 with certain
    extensions (there are around 8 that cause problems).

  * The PHP upgrade itself is pretty harmless. Check your logs for
    deprecation warnings. If there aren't any, you can probably just
    switch to 7.0 with eselect and have everything work. It's a lot
    faster and a bit less stupid than previous versions.

In any case, to bring this back on-topic, dev-lang/php now has a webp
USE flag too, so +1 for making it global.
