Sorry, I'm copying the bug list now.

I think guessing "lang" from lang-mode is perfectly fine. The problem here
is that when eglot-server-program lists a server for tex-mode and the
server is selected for use in a derived mode such as latex-mode, the
guessed language is tex and not latex.

For the reason noted above, there is no "concise solution" to choose, all
derived modes from tex-mode need to be mentioned explicitly in one way or
another (either to make the guess correct, or to provide manually a
language id).

Fine, I can change the patch so that texlab will still run on modes that it
doesn't support (plain TeX and ConTeXt, etc). Just please confirm that this
is the behavior you prefer.
