It isn't supported by Tramp yet. Tramp hasn't heard ever about.

Of course, and I did propose to add it. I just wanted to avoid an
inflation of proposals for primitive operations being supported by Tramp.

And yes, not all backends need to implement an own version of
`directory-files-recursively'. But this could happen for other primitive
operations, so we must always think about whether it is worth to add a
primitive to Tramp.

Best regards, Michael.
