I think this approach might be problematic if the major-mode provides a
"declaration" type and, say, Eglot provides a "definition" type.  But
maybe, as you write, providing customization options to the users is a
simple solution in this rare case.

Currently all I write are emails, but long ago I wrote a simple,
tmm-based completing-read function to overcome this problem.  Maybe that
approach is useful here as well:
