Tested manually in Chromium; the original CL breaks, but patch set #2 succeeds.

These metrics/field_trial default targets are of tricky. I guess we should do
those targets testonly=true so we don't accidentally depend on them in
production code. I'll look into that.

Yes, that sounds like a good way to catch this sort of error at an earlier
stage. (In combination with a comment that explains why it's testonly and what
targets should and should not depend on it. Also a comment on the target with
the headers that explain where to get the implementation.)
