Really? It's not common? I do it all the time. Is there some reason it's not
common?

Not particularly - it's just not something I see that often.

To give you an example, for most of my larger apps, I have generally create
some sort of plugin framework (I'm still trying to come up with a good,
reusable plugin framework, but can't seem to accomplish this). Normally,
I'll create interfaces which are implemented in the main app, usually
something like an IApplication interface. Then I'll have events that get
triggered for things such as initialization completing, app shutting down,
windows opening or closing, or whatever.

Those all seem like perfectly good examples. There's nothing wrong with
them at all - it's just not that common. For instance, I don't think
there are very many interfaces in the framework that specify events.

(Of course, now I'll find there are hundreds...)
