That's an argument about UI interaction style.  And
the "only" is the real key to what's misguided.

Different users can prefer different interactions.
Different coders can prefer different interactions
for different calls to `completing-read'.

There is no one-size-fits-all.  `completing-read'
is extremely general, allowing for many different
interactions for many different kinds of use cases.

Even if Godot proclaimed that ONE style of use is
"better" for most interactions, that's not, in
itself, a reason to not provide also for what
INITIAL-INPUT offers.

BTW, independently of this discussion (and even
independently of completion), there should be a
single key to empty the minibuffer.  (Icicles
has provided `M-k' for that forever.)

That may make more sense to you.  It may always
make more sense to you.  It may make more sense
to you in that example.

Those preferences might be arguments in favor
of providing ways for a user to configure such
preferences.

None of them is an argument why INITIAL-INPUT
should be deprecated.

That you don't want INITIAL-INPUT is one thing.
That some library might not make a good decision
about its use is another thing.

Whether INITIAL-INPUT should be deprecated is
a third thing - something completely different.
