Agreed, and the same is true for hexl mode.  But for a reason to be
good it need not require existence outside Emacs.

Well, I have some commands that let you set or examine or search etc.
such properties.

But I agree that we don't have such UIs in vanilla Emacs.
But we could, and I, for one, would welcome that.

I agree that it need not be in Emacs core.  I'm just welcoming the
feature.  From my point of view it could be a 3rd-party library
on MELPA.  Or it could be in GNU ELPA.  I see no reason for it to
be in "core" vanilla Emacs, or even in vanilla Emacs.
