That's certainly true. However, it's a runtime dependency to enable a
new feature, and shouldn't cause any breakage without that patch, so we
don't need to be explicit about the dependency in git.

That's also true. I wonder if we shouldn't support this in the regulator
core bindings instead, since the existence of a parent regulator seems
likely to be common. Either way, I'd like to include the property to
document it for now.
