Does anyone use immersion cooling for dedicated servers as a provider or as a customer? What are the pros and cons?

I'm curious to know if anyone has had any experience with immersion cooling as a hosting client or as a provider, using it in practice or ever experimenting with it?

Got a chance to play around with immersion cooling in one of our side setups, surprisingly efficient, especially with high-density workloads.
The maintenance side is a bit different, but once you get used to it, it’s kind of satisfying.
Not mainstream yet, but feels like it’s getting there quietly.
