Why so? `directory-files-recursively' is already supported by Tramp via
`directory-files'. But at least for some backends
`directory-files-recursively' may be implemented more efficiently. If
other backends do not implement it, `directory-files' will be used.

I hope that the above approach with only some backends implementing such
support will not add too much of maintenance burden.
