std::format support?

[Zopolis0 via Gcc]

There was some discussion around std::format support 2 years ago, with
people suggesting to just use the fmt code, and others suggesting that an
independent implementation might be of higher quality. 2 years have since
passed, and we have no implementation, of higher or identical quality.
Could we come to a decision on this? Having no implementation whatsoever is
the worst possible outcome.
