I agree that there are cases where INITIAL-INPUT still has its place,
but as I said, I remember the reason for phasing it out was different
than stylistic preferences.

True, unfortunately.

I presume you've suggested this addition to Emacs?

Not sure about this one.  I mean, Emacs has a lot of external (i.e., not
maintained in core) libraries and it would be a major advantage if they
all feel the same when you use them.  Hence, I understand the general
direction of "deprecating a feature" to streamline the look&feel, but
you're still free to use the old feature if you think it has a added
value from a user perspective.  In my example above, it wasn't a good
decision, so I changed it.

Best, Arash
