After thinking more about it, I came to the conclusion that we should
stop sanitizing *-stats lines at all.  As you pointed out, we never said
that we'd sanitize them, so I tried to draft a sentence or two why we
remove cell-* and exit-* lines.  But I failed to come up with a good
reason.  Removing those lines doesn't hide bridge locations any better
than leaving them in.

As a result, the only thing that's sanitized in extra-info descriptors
is the bridge fingerprint, similar to how it's sanitized in server
descriptors.

Best,
Karsten
