What's that?  Modulo bugs (one of which you've fixed recently) the "dumb"
is the most passthrough one, except for the completion-ignore-case.
Do you want to remove that?  I added it at some user request... seemed
reasonable.  Maybe it's not.

There is no way to do that.  We don't have a say in what the server
gives us.  If the user types foo and the server ignores "foobar" and
prefers "farfromsober" or std::foobar for whatever scoring reason, then
there's nothing we can do about it.  These users are continuously
misinformed  about LSP inability to follow Emacs's completion styles,
despite my frequent admonishing.
