I think it pretty much comes down to a personal preference. I could also
imagine that there could be a single "IUIServices" context which would
provide access to the UI services. But having the capability to inject
whatever is available in the context would definitely be a great helper.

What I don't like with such reflection magic is that it makes it more
difficult to understand the code. It's not simple anymore to search for
callers of a method (Ctrl+Shift+G). That's why I would prefer having a
visible contract.

That's a good point. Is there any progress in relation to e4? I
understand that this is a work item on the e4 list.
