That's exactly Michael's point: that Tramp can't know that the current
operation is part of some kind of completion, just by looking at which
Tramp functions are called.

The question is: does Tramp need to know whether or not this
`directory-files', or `file-directory-p' (or
`file-name-all-completions', which may also be called in non-completion
contexts) is called as part of a completion operation?
