Just to clarify, you can run as many LSPs in a given file type as you want.

Common features like completions, diagnostics, and auto-formatting will multiplex to all of the LSPs.

Admittedly, there are certain features that currently only use one LSP: inlay hints and document highlights are examples. For which LSP features is multi-server support important to you? It shouldn't be too hard to generalize.
