As with all technologies, you have to use the for quite a while before
it all sinks in. Even then, there will remain things that somehow
remain difficult to understand. For example, what does <? super T> mean
here in this Collections method?
public static <T extends Comparable<? super T>> void sort(List<T>

Yes, a pragmatic approach to modeling that maps particularly well to Java.

Drawing on the screen rather than on paper. I imagine it helps a lot
when you make an error to be able to undo it, but at a deeper level, the
design process is the same.

Many is a relative term...

Yes, I don't believe there is a one-size-fits-all approach to modeling
in general. EMF provided a model for describing models, so it's "more
general" in the sense that you'd use it to build specialized models,
such as UML, SysML, XSD or whatever.

I imagine EMF will be well suited for that.

I'd suggest trying one of EMF's tutorials. That should take an hour and
should give you a better sense of what's possible, especially if you
keep in mind that the same things you can do with something like the
simple Library model is what people have done to build the XSD and UML
