It's an argument against not flipping "make installing them be optional"
flag on by default, but we could otherwise move some of t/helper to
builtin/, which would help by encouraging us to write at least
boilerplate docs for them.

Git developers & similar parties could then set them to be installed for
ad-hoc debugging.

Whatever anyone things on that, just on Taylor's "begin to depend on"...

I really don't buy the argument that there's no amount of warnings in
our documentation that we can include which would give us future license
to willy-nilly change certain things.

If that is being argued then that seems to categorically exclude certain
other things, e.g. including "scalar" in-tree at all, because if we
can't trust users to read the warnings about it being "contrib-y"...
