that's possibly closest to the intent of the qid discussion in intro(5), although
it's not clear that considers the possibility of aliases within a hiearchy,
where it might make more sense to have the Qid.path associated with the file,
regardless of how you got to it. even so, for dump it's not been a big problem
in practice only because one usually binds from the dump, not into it.

i'm sure that somewhere it was suggested that high order bits of Qid.path
should be avoided by file servers to allow for their use to make qids unique
but i haven't been able to find that.
