Why wouldn't you want the lint error to be highlighted right as you type the code?

gopls has staticcheck and govet warnings; they are quite useful as you're typing in your code. (Though sometimes a little aggressive. My favorite is highlighting an if statement as an "empty branch" before I've had time to type in any code. I'm working as fast as I can, Mr. Linter!)

eslint's flymake integration can do this without any language server commitments. LSP maybe offers some performance advantage - but IMO that says more about eslint than LSP or flymake.

Why do you think you need to involve an LSP for that?. ESLint, as most linters, can take their input from stdin. That is exactly how the eslint-flymake[0] works. Lint on buffer contents, not file on disk. No JSON RPC involved.
