Everything you said is correct.  The committee is ready to vote,
but it is still a none existent standard.  The first thing required
for gfortran to support any F2023 feature would be the addition of
a -std=2023.  This has not been implemented, yet.

I'll also note that things don't magically appear in gfortran.
Someone has to implement it.
