TeXLab is not the only LSP for *TeX.

https://github.com/astoff/digestif merged ConTeXt support including some TikZ
wrapping for ConTeXt etc. (Have a look at PR #24.)

It is written in Lua, so if you feel more native there you could contribute.

If someone would extend TeXLab that would surely benefit many. But they seem
much more hard-wired towards LaTeX.
