You can't check if a component uses 2.3 functionality, so if we just
upgrade we might end up with a not 2.2 servlet compliant solution. (Or
is there a way?)

Servlet 2.3 has been released more than 4 years ago[1]. IMO it is safe to consider that people using recent versions of Cocoon are running at least servlet 2.3 and most probably servlet 2.4.

So depending on servlet 2.3 shouldn't be that much of a problem.
