You might have missed it in this long thread, but my proposal was to
obsolete eglot-move-to-column-function and eglot-current-column-function
now and remove them in after several Emacs releases.

The rationale is that these vars were introduced to work around
nonconforming servers.  With the new LSP capability, there should be no
excuse for nonconforming servers to exist.  They should all adapt in the
medium term.

So yes, I have no problem admitting my approach looks uglier today, but
it's clear to me that it would lead to a cleaner result in 2030.
