On of the things with vim/neovim for me what was a deal breaker is that you could not turn off/on LSP's for different projects. So neovim got slow for me. I also don't wanted to copy my config for each project.

Does Helix have a solution for this?

For what it's worth, you can definitely disable autostart conditionally in nvim-lspconfig, maybe using on_new_config and setting autostart=false therein.
