(I'm going through old bug reports that unfortunately got little response at
the time.)

The way Emacs is messaging things has been changed a bit in Emacs 28,
and fewer messages are overwritten in general, but I'm not sure whether
this also covers the eldoc messages being discussed here.

Do you have a concrete case where eldoc is overwriting a message that it
shouldn't?
