This message would be logged, usually multiple times, for EVERY. SINGLE. PIXEL. That's pretty much useless and just makes the log unreadable. Plus, the current support (which acts as RGB8) is close enough that for end-user purposes, it's fine. I don't think the hardware backends support RGB565_Z16 and its antialiasing functionality correctly either, but they don't have similar logspam.
