Should I try to fix rebase interactive preserve-merges bug

[Wink Saville <wink@xxxxxxxxxxx>]

There is a "TODO known breakage" in t3404-rebase-interactve.sh:

   not ok 24 - exchange two commits with -p # TODO known breakage

I'm contemplating trying to fix it. But with --recreate-merges coming
maybe it's not worth the effort. Should I proceed with attempting a
fix or is --preserve-merges going to be a synonym for
--recreate-merges?
