Couldn't refactor-apply-edits be replaced with something that doesn't
depend on the rest of the library?  I'd prefer not to delay the fixit
support in Eglot until we decide whether or not to add refactor.el.
Adding refactor.el could then be a separate discussion (and I do think
having refactoring capabilities in Emacs is long overdue).

Thanks.
