Not solely with the `s' library; there are a few others.
But basically I think you are right about this.
And this is indeed the main intended use in Emacs itself.

I would not object to making rules about naming or usage conventions
for the shorter names, in the second use-case.

We can't follow those conventions for the first use-case.  They would
not work.  But it is ok to treat the two use-cases differently.

I think #2 might be a good idea, but #1 would lead to horrible
confusion.  If the screen does not match the buffer, that is chaos.
