What I meant by "serious limitation" is that the condition a.) might mot
hold true.  You might be rebasing / rewriting the commit 01a9fe8, but
there might be some commit not undergoing rewrite (for example one on a
separate branch) that refers to the commit being rewritten, e.g. by
including "revert 01a9fe8" in the commit message.

We also need to assume that the commit referred to (i.e. 01a9fe8) is
being rewritten earlier in sequence than referring commit (i.e. one with
"revert 01a9fe8").
