A few years ago when this last came up, I ended up digging into a bunch
of USE=ipv6 providers and found that USE=-ipv6 either didn't build, took
a less supported (non-default-upstream) codepath which looked bitrotten,
only toggled default configuration (sometimes via the build system). I
also found several cases where it ended up taking a legacy code path
while the USE=ipv6 one used modern networking functions which happened to then
support IPv6.
For a case like the latter one (and the rest I mention, really),
disabilng kernel support is more appropriate.
But read on wrt PHP.

I think what you really want is
https://github.com/pkgcore/pkgcheck/issues/478 because you've made the
case as its maintainer for the flags to exist. The discussion really
ends there in such a case given you're considered the matter and decided
it has value in PHP.
The issue is therefore just having a suppression for pkgcheck. The
pkgcheck rule was intended as a hint that something might be suspicious,
rather than indicating it must be removed.
thanks,
