Thanks again for this work Michael.

Unless there is other feedback soon, I'm inclined to release this as
CGI::App 4.0, pending my own final review. 

If the callbacks need some refinement after launch, I think we can do
that fairly safely as this is a new feature that I expect relatively few
people to begin using heavily just after the release, relative the
CGI::App installed user base.
