No documentation promised that the previous message will not be
cleared when inhibit-message is set.  We just avoid displaying new
messages.

We could extend the mechanism to allow it to prevent the clearing as
well, but that would probably mean inhibit-message will have to be a
tristate, because by now it's too late to change what its non-nil
value produces.  So we'd need to introduce a special value (not nil
and not t) which will have this effect.

I don't understand what that has to do with the dont-clear-message
thingy.  That is about something else: it prevents clearing the
message when there's an input event, like if the user types some key.
I see no reason why we should remove that feature.

Please keep your contempt for other people out of the patches, if you
want them applied.
