To step back a bit, the way I see it, the main goal as a language designer is to ensure that users can be productive in the language. Many factors play a role here. Language features are an obvious one, but there's also (in no particular order): standard library, ease of integration with other code, documentation, community, tooling, etc. That's a lot, so as daxfohl says, picking your battles is key. Not everyone will agree on the relative priorities of these factors, and that's totally fine too. However, I personally think that tooling is (one of the) super important factors. "Fast & snappy tools" is actually one of the explicit design goals for Muon [1] (design principle #12). So releasing a language server so early on in the life of the language underscores that, yes, Muon is a language with a strong tooling focus, and I hope that resonates with people.
