I think I agree with you. When I was part of a growing F# team a number of years ago, everyone we hired was an enthusiast who just loved coding in F# and wanted an opportunity to do it professionally. It turned out that this love, combined with the constraints of the language, led to a super-clean and legible code base. The quality was (in my estimation) outstanding, and I was sad to leave it.
I'm at my current company (actually writing mostly typescript and node services now) because of a YC "who's hiring" post that mentioned F# positions (bait and switch /s, but my experience lined up heavily with the team I ended up joining which didn't use F#).
