Yes, I know.  That's a misfeature, IMO - a regression
for users and libraries - but it was done on purpose.

It should have continued to be possible for `message'
to temporarily write to the echo area (yes, hiding
the minibuffer temporarily), instead of being co-opted
by the `minibuffer-message' behavior.

Instead of having both behaviors possible, and thus
usable for different purposes, they are collapsed
into only the `minibuffer-message' behavior (write
at the end of the minibuffer, instead of to the echo
area).
