Of course, I'm glad that TexLab project does provide LSP support and bringing it to the Kakoune editor as well, but I'm sure that many of you know that bringing ConTeXt support to TexLab would benefit users of **many** other editors since these today many most popular editors (Atom, Emacs, SublimeText, (neo)Vimn, VScode...) are having support for LSP.
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.
Unfortuantely, I'm ConTeXt noob and not speaking Rust, but just want to bring the information if there are people familiar with both about potential benefit for ConTeXt to get LSP support.
If someone would extend TeXLab that would surely benefit many. But they seem much more hard-wired towards LaTeX.
