What is wrong difficult about changing to a fixed revision of an external?
It is recomended in the book:

That is an option in your specific case only (you have control over your external).

A client side wrapper (no, we don't have client side hook scripts) that fixes all externals to their
current HEAD recursively. Or just some, but that will be PITA as a CLI.
