Yes, I meant adding code that would support functionality not
available when 'ls' is used.

That's trivial: there always is, including in ls-lisp.

Why?  Personally, it would mightily confuse me: I always expect to
find all the dot-files together.  This is useful, e.g., when I'm
looking for init file related to some feature, but I don't know the
exact name of that file.

But if 'ls' supports that, so should ls-lisp.

Isn't this what "ls -v" does?  If so, and if ls-lisp doesn't currently
support that, patches to add such support are welcome.

Patches to support any feature available in some 'ls' are more than
welcome.  TIA.
