Hi Ko,

Thanks for the feedback. I've pushed the patch to the repositories,
slightly modified. It will appear with Emacs 29.2 as well as on GNU ELPA
later this week, as Tramp 2.6.1.3.

Yes. tramp-sshfs.el does not offer an implementation for
`vc-registered'. To be precise, it offers the function

--8<---------------cut here---------------start------------->8---
    (vc-registered . ignore)
--8<---------------cut here---------------end--------------->8---

Therefore, all files are not under VC control. This won't change.

Pls tell me if you see more optimization knobs to be implemented. ATM, I
believe we have done what's possible with this bug, so I'm closing it.
