I also don't agree in enabling tooltip for a disabled components [1],
since this would be just bad design.

I think one possible way to solve this elegantly is to have a small text
in close proximity to the disabled component specifying the action
needed to enable the component.

Nevertheless, even if it's clear that the toolkit should not enforce any
particular habit in UI design, in my opinion it should also try to
address the developer away from clearly wrong or confusing patterns,
especially when supporting those patterns means cluttering the API.

I can't see a reason why a disabled component needs to receive events.

I don't think this is horrible. It's just as inelegant as the problem it
tries to solve.
