Having code we don't use is a maintenance burden without benefits.  If
local patching is an issue, perhaps you could rewrite the code as a
module?

But I actually still don't understand why you took such a radical step
and removed everything except the primitive.  I think this is a
valuable debugging feature, of which we don't have enough in Emacs.
Would it help if I volunteered to produce documentation from some
explanatory unformatted text that you could provide?  Or are you
refusing to document this out of some principle?  Or is something else
a matter here?
