That's moderately insulting. To me, at least.

I just posted a summary on 24/11/2023, 03:37 +02:00. Do you perhaps have 
any questions related to it?

One of the disagreements is on whether Xref should have any new 
kind-commands, such as xref-find-declarations, xref-find-implemenetation 
and xref-find-type-definitions which you can find on the branch 
feature/xref-find-extra (the diff is not big, you can take a look).

Or whether definitions like that should be reimplemented by every Xref 
backend that wants to use them, and the backends would themselves pick 
the key bindings for them (or leave unbound).

The usefulness of this also depends on whether we can appoint a 
comfortable binding for the prefix map for the new commands. In the 
prototype I've used "M-'" -- a binding currently occupied by a command 
that I've never used in my life, which others here seemed to agree with 
-- but any other alternative can be considered, of course.
