Totally. Developing against internal APIs is always a pain and it takes a special kind of motivation to keep a project like this alive for as long as he has.

I can understand the core team as well though. Doing what null-ls is kind a nice in principle, but 90% of what people is it for can be done differently without hooking deep into the LSP client like that. I get why they don’t want to commit to opening those APIs for what seems to be mostly niche cases.
