This would definitely help for some things, but it doesn't solve what I
was talking about.
What about a _single_ update that needs recompiles of dependent spells?
Triggers don't help here as those spells can't know about that recompile
dependency before it happens. It's something cleanse --fix usually
catches nicely, but I want a way for gurus to document that so the QA
team can put it in the release notes of the stable grimoire.
