Me joking? No way :) (Just kidding)
Don't worry about this :)

Yes, that's true. Now, at some point we have to break compatibility to
get a cleaner architecture and
an even better way of doing things. Perhaps removing sub sitemaps is one
 of these things, perhaps not.
But on the other hand there are many applications out there using this
stuff and they don't want to migrate. There is no real benefit for them.
But there is benefit for them using latest and greatest Cocoon for now
stuff. And this is very I think embedding 2.1 in 2.2 might make sense.
It allows people to run their old applications without modifications
while at the same time they can start new apps with 2.2.

As Cocoon 2.2 uses Spring as the container and as the Cocoon beans are
added to the Spring root container, these things are available in 2.1
through Spring as well. So people are able to call 2.2 stuff from within
2.1. It might be a thin bridge in terms of possibilities but I think
going this way makes things easier.
