And there is no justification behind that "_should_" claim; you are
not making any technical argument to explain it.

Of course it has to be hypothetical; I already said with the current
code no standalone does use it---it is not arranged to be doable so
there is no user.  If you want to have examples of future possible
callers, they have to be hypothetical---the future by definition
hasn't happened.  But that does not mean hypothetical is impractical
nor useless.

There are out-of-tree programs like cgit that will not be built-in
but already link with libgit.a.  Moving things that can be used by
outside people out of builtin/*.o to libgit.a would allow uses that
you and I cannot imagine offhand.  I do not see a reason for us to
forbid a filter-branch replacement out of tree as a standalone.

I do not see a point in continuing to discuss this (or any design
level issues) with you.  You seem to go into a wrong direction to
break the design of the overall system, not in a direction to
improve anything.  I do not know, and at this point I do not care,
if you are doing so deliberately to sabotage Git.  Just stop.
