I would vote against that. A compiler would catch an error if someone
is using a return value of a function that returns void. Why make
names longer and harder to read?

I think this goes way beyond cbdata purpose. In my experience, such
hooks are making things simpler *on the surface* but lead to awful
dependencies and hard-to-find bugs. Humans have trouble thinking
non-linearly or in-parallel and hooks that get called on some event
require such thinking. I would prefer to avoid them as much as
possible. It is just my opinion though.
