How about forbidding PATH to be a repos-relative URL, but permitting it
to be a relpath, that is then interpreted relative to the repos root.
(I would say permit it to be an fspath, which is by definition absolute,
but fspaths aren't part of the public API.)
The conversion is trivial, just +2 on the argument, but it avoids
"non-canonical" and "^/ URLs" in the repos API.
