Re: [GNU ELPA] eglot-x.el: Protocol extensions for Eglot

[Felician Nemeth]

I can surely try to submit these extension one-by-one as patches to
Eglot, but my first attempt was friendly rejected, so I think a package
collecting these rejected extension is a good thing.  Also, even my
patches implementing standard LSP features take a long time to be
processed, so temporarily collecting some extensions in the eglot-x
package allows me to work in my own pace.

Sometime ago, I collected the internal variables, functions, and advised
functions that eglot-x uses from Eglot in order to help to refine
Eglot's public API:

If it helps, I can explain one by one why it was necessary to use them.
