I think it is useful. I did something like that creating a super-repo
for performing a bisect over EGit and JGit over a period over a year.
I don't think I restricted myself to the first parent, which was probably
a mistake.

The solution isn't perfect, but provided that is well-known you can
live with that. A problem I found was that many stiches versions weren't
even compilable so one might want to have the option of matching commits
using a window of some sort to identify compilable combinations and have
the ability to use only those for bisect. I'm not sure it's practical though.
