For a long time I'm trying to solve the upper problems.
It would break (well extend) the servlet spec if we offer
to webapps that we do that automatically for them.
That way user would just provide a standard .war telling
what part of the webapp should be loaded by parent class loader
(making that singleton for the server lifetime of course)

On redeployment those resources won't be redeployed
until the full server restart.
