It's not the exact opposite. Portage is still telling you what it needs,
but all in one go, not one problem at a time.

Not only contrived, but irrelevant. Because tcpwrappers actually does
something. If your USE flags are unsuitable, portage actually does
nothing. All that's changed is how it tells you why it has done nothing.

I must admit, although I read about the new option, probably in an elog
message, I was surprised the first time it kicked in when I hadn't turned
it on. Although it was not a bad surprised and I then recalled that the
message had explained that this was now the default behaviour.

One of the unwritten rules of Gentoo is that if you don't read elog
messages, you can expect to get burned.
