It's already possible to deal with this problem by creating a new
branch where the bug is fixed, and then using "git replace", so that
the new branch is used instead of the old one.
Please search for "git replace" in this doc:

Perhaps some people would find it easier to use what you suggest but
using git replace may be nicer because you have to create the new
branch once, so you need to fix merge or rebase problems only once.
And the new branch may be useful not only for bisecting, for example
to recreate old versions.

Thanks,
Christian.
