What I proposed is not removing that possibility, just making user n/w
and program n/w two different facilities; one is a user commodity, and
the other is (low or medium)-level infrastructure for elisp libraries.
That the two are conflated is the result of library auhors not having
other equally easy way to show selected parts of a buffer, I guess.

No one has been proposing less user control.
