I use eglot+Tramp with various containers (nspawn, docker, podman),
which don't support the ‘tramp-direct-async’ flag, so I'm not sure how
helpful this testing would be.

I know we've spoken about that flag before, and I came away from those
discussions with the impression that those methods should not support
direct-async, but I'm unsure why. I have only skimmed the relevant code,
but it seems like there shouldn't be a problem with supporting
direct-async on the container methods. Is there some danger I should be
aware of?

If it's safe enough, I'd be happy to flag support for direct-async in
the methods and do the above test.

WDYT?
