Also, is there a motivation for introducing this new requirement, seeing as
how we've never had such a restriction in the past?
Some cases I've come across (for lsp-mode, which is currently not idempotent):
- Enabling a minor mode in both a parent and a derived mode hook.
- Restoring buffers from the desktop file.
In such cases minor modes are activated twice, causing errors if they are not idempotent.
