Err, for-each-ref already uses it before this series, no?
So, you don't need any extra option to get for-each-ref, because it is already there. Having these extra options is a good side effect, though.
To make sure I'm clear enough, what you're doing is
- add all options to for-each-ref - port tag.c - port branch.c
What I'm suggesting is to prioritize this way
- add all options required for tag.c - port tag.c - add all options required for branch.c - port branch.c

Not only the challenge, but also the way to validate your work. Think of it as a rather comprehensive set of tests that you get for free once you ported a command.
BTW, talking about tests, did you do some coverage analysis on git branch and git tag? If not, I'd suggest that you do this to make sure that the pieces of code you're rewritting using ref-filter are well tested before being rewritten (a bit like Paul's work on shell -> C). You don't have to actually do this before porting, but it should come befor the port in the patch series to make sure that tests pass both the old and new implementation.
