Yeah, the MySQL interpretation of this is basically as a shorter form of
Postgres's DISTINCT ON syntax. There's something to be said for MySQL's which
doesn't introduce an orthogonal syntax to GROUP BY with basically equivalent
meaning, but there's a lot to be said for having a syntax that you can't write
by accident as well.
