I think there are probably two separate (but somewhat related) issues:

1. LSP over Tramp is "slow". I'm sure there are things we can do to make 
Tramp faster, especially with "well-behaved" remote hosts. For example, 
maybe Tramp can get more info about a host upon connection and then use 
that to avoid some work later on.

2. LSP over Tramp is "unreliable". I think this is the more-pressing 
issue. It's one thing if a remote request takes longer than expected, 
but another thing entirely if it just fails to work every so often. When 
trying to use Eglot + Tramp on some larger projects, I'd get hit with 
"Forbidden reentrant call of Tramp" every so often, which, if memory 
serves, usually required a bit of poking at Eglot, or at least retrying 
the operation I wanted to do. Maybe this has improved since the last 
time I tried this, but (I think) fixing these errors would go a long way 
towards resolving people's complaints. That's probably easier said than 
done though...
