I think this will give ample means to experiment because you can put
whatever you want into your components.

Once I'm done with the maven plugin I will augment the plexus plugin. I
need this stuff asap so this one won't linger. This will make for a
fully mutable framework where your differences from the core can be
isolated and easily managed. You can basically strategize your mutations
and try each of them by weaving a particular aspect across all your
components.

We can also start making a library of useful aspects for plexus as we
can now store them in JARs for sharing. I would definitely like one for
profiling. I have not tried any runtime weaving and I'm not entirely
sure that has been fully worked out but it will soon come with AspectJ.
But even if you needed different aspects used for a particular runtime
requirement you can work around it by weaving in all the aspects and
using a runtime property to control whether the aspect is used or not.
Basically an if within advice to control the execution of the advice.
