FWIW, I think `sweeprolog`, my NonGNU ELPA package for SWI-Prolog can
also a good non-LSP backend.  Elisp would be perfect, no doubt.
But `sweeprolog` is interesting because it does a lot of code analysis
that's useful for refactoring.  Namely it provides precise project-wide
cross-reference data that can be used for renaming predicates.  Renaming
local variables is already implemented, with a simple UI: you type `C-c
C-r`, it prompts you for a variable to rename in the current clause
(with completion), you hit `RET` to choose the variable at point, you
insert a new name, and it renames the variable at once.  That's alright
for renaming local variables, but it would be great to simply plug in to
a generic refactoring UI.

So I can probably try and implement any "refactoring backend functions"
the new refactoring interface includes, and see how it goes.


Best,
