In 3.x I understand how to define extension points and contribute
extensions to those points. What I feel I am missing is what is the
model for how to handle this in a pure e4 way? IIRC, defining
extensions the 3.x way will force the use of the compatibility layer.
ATM I don't have a real issue with that, however I still would like to
understand what should be done if you want to go pure e4.

Looking back I see I tied the discussion from the "Pure e4 Application
with old UI extensions" newsgroup thread to the use of the compat.
layer. Now as for DS, there is definitely some overlap between what the
registry does and what DS provides. And in some cases it comes down to
6 of 1 and half a dozen of another where it is just the developer's
preference. However, as an e4 best practice, eclipse should be leading
as to which way we should go. That way most devs will have the same
model making integration easier.
Also IIRC DS is not usable for extensions that are data based like help
content plug-ins. A dev could define an interface that provides all the
info, and put implementations into DS, but it seems overkill in relation
to just using the registry.
