Putting git tags in the "rcl" URL parameter works for me:
https://cs.chromium.org/chromium/src/DEPS?rcl=16.0.909.0

What did you try that didn't work?

Nice, I hadn't tried that but it works.

Once I'm at that URL, do the cross-reference links in the code reference the same revision? I didn't see any visual indication one way or the other.

Ping: can I get an answer to the question in comment #2 about whether the cross-reference links reference the same revision?

If they do then I'm good to use the tag linking. Otherwise I'll need to wait for this to be supported.

Oops sorry.  Nope, cross-references only exist for HEAD, we don't keep their history at all.

Ah, that's too bad. Having people browsing inconsistent revisions would be super confusing, so I'll have to wait for the revision-specific cross-referencing to be supported.
