It wasn't accepted at that point - review 3 has happened during
which Andrei has reconsidered his std.experimental acceptance
criteria and it got accepted with no additional voting.
The tricky part about being review manager is exactly that there
are no strict rules. In the end it is all about ensuring Phobos
quality and stability and sometimes arbitrary calls had to be
made.
I personally consider replacing vibe.d native logger a crucial
blocker for accepting std.experimental.logger into main namespace.
