Having one doesn't really help because everyone has different needs,
you need to support arbitrary event handling systems as part of your
library's API.

As far as I'm concerned most of these things shouldn't even come with
their own event solution, however that's likely an unpopular view
because people like things to work out of the one big box, regardless
of how useful that actually is in the long run.
