Because you've asked why/how not using INITIAL-INPUT with
completing-read has an improved user experience.

But it has nothing to do with completing-read.

Huh? Completion is a must especially when there are many and similar
completions. Would you consider M-x/C-h {f,v,etc} without completion
being a good user interface?

Sure. But the thing is that people writing packages usually don't
provide an option if INITIAL-INPUT should be used or not. Therefore,
whatever choice they make is forced upon their users (well, unless the
user knows of :filter-args advices). For that reason it makes sense to
document a guideline on how to do things as Arash cited in
<86mte3lsj2.fsf_-_@gnu.org>.
