We "the Emacs code" do. But it's not obvious to a user. The commands
that invoke these things are global, remember. I very very often don't know
where I pulled C-h o from. And I don't want to know. Sometimes I do,
sometimes I don't.
In summary, I wish we can keep the what has been the invariant of Elisp
ever since it was created, and which is underlined many times in the manual:
there is only one obarray of symbols. I believe my stance preserves this
accurate mental model more than yours.

"should NOT allow". That's what I am saying, yes. Any command that operates
on _symbols_ should not offer shorthands as candidates unless the goal of that
command is to directly modify the buffer where those shorthands have meaning.
So C-h o is in the former group. C-M-i s in the latter.

I don't agree, but ultimately it's your call. Notice (maybe watch the
.gif again),
that what happens when you type C-h o on 's-concat' is that the prompt becomes:
"Describe symbol (default magnar-string-concat): ... "
It does _not_ become:
"Describe symbol (default s-concat): ... "
Because 's-concat' is _not_ a symbol.

It hasn't in SLIME/SLY and package-local-nicknames have existed for
quite some time there.
What is your opinion on the visually annotating font-lock idea? I think
it's useful even if we decide to go with levels 2 or 3 of the above
integration (which, as I said, I think we shouldn't, not for now)
