What

The directory-sync client no longer has the call that attached a session file to a mount path, along with its upload request and its guard against mount paths the server would reject. The capability is removed, not renamed.

Evidence

dir-sync: refused to attach a session file under a mount path or id the server would reject

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
