bug#34939: Some minibuffer behaviour is annoying

It will block `message', not messages.  It will hijack
`message' to effect instead `minibuffer-message'.

That's not right or fair.  Code that calls `message'
should get `message' behavior.

Which means that code that _intends_ `message'
behavior, which does (temporarily) replace your
input in the minibuffer, no longer does that.

No way around it - `message' just gets hijacked.

It is so _easy_ for any code to explicitly call
`minibuffer-message' when it wants that effect.
But now you want to make it impossible for code
that calls `message' to get `message' behavior.

Not needed and not the right thing.  You're
impoverishing Emacs behavior by replacing two
possible behaviors with one.

No, it does not.  User input cancels the `message'
text.  And this is during an overall input reading,
remember?  And code that calls `message' can invoke
`(message nil)' to also cancel the `message' text
at _any_ time it deems appropriate.  There is no
mandatory 2-sec wait, such as you suggest.

If you think there is a _particular_ context or
use of `message' that is problematic then fix that.
What you're proposing/doing instead is smashing
with a sledgehammer.

Ridiculous exaggeration. I use `M-n' all the time
and have never had to wait like that.

This is a bad idea.  If you want to let users opt
in to such a reduction in behaviors then fine, please
do create a user option that lets them opt in for that.
No one will have a problem with that.
