Not just the delay. You need to be _able_, somehow, to specifically get the
normal `message' behavior even when a minibuffer read is in progress. See my
reply to Juri.

Again, the simple test of "in the minibuffer" (or even whether the minibuffer is
active, which is more appropriate) is not appropriate for all cases. You need to
be _able_, somehow, to specifically get the normal `minibuffer-message' behavior
even when  not in the minibuffer (or even when it's not active).

Currently, a programmer can get any of the behaviors discussed, including the
conditional behaviors. Please don't replace that flexibility with a single
one-size-fits-all behavior.

If change there must be, please choose #3. Any name you like.

See my reply to Juri. `minibufferp' returns non-nil for every minibuffer,
whether active or not, and it returns non-nil for a minibuffer even if _none_ of
the minibuffers are active. That is, it returns non-nil even if there is no
user-input interaction going on. That is the wrong condition.

The proper test, IMO, is whether the minibuffer is active, that is, whether some
minibuffer is active. It has nothing (necessarily) to do with the current
window/buffer.
