Agree with you, however as find_duplicates operates BB by BB, it would require
introduction of some kind of dependencies (e.g. you can merge BB1 with BB2, if
BBx would be merged with BBy). I can write it on my TODO list after we'll
transform tail-merge to IPA ICF infrastructure.

Does it work for you?
