So, just syntax highlighting is not compelling to move out to a server. But part of my idea is that if you have async to hide server latency, so it's not slowing down typing, maybe you can do a much deeper analysis than just surface syntax. Right now you get basically instant coloring and then much slower but more accurate feedback that's generally comparable to an incremental recompile. I was thinking that a language server might be able to give you quick feedback on some aspects of your program before having to do all of it. Perhaps an even better motivation is indentation. When I use editors with regex-based indentation (the norm), I'm regularly annoyed when it gets it wrong. Being able to budget a few milliseconds or tends of milliseconds to do indentation that exactly matches what rustfmt or gofmt would recommend would be worth it, imho.
