Thank you for your patient and informative replies.  Unfortunately, I am
currently not interested in package-specific optimizations, that is not
my goal.

I will be the first to test the global transformations, but right now I
will have better returns on my time investments in other projects
including a router system and continuous integration of my channel
updates.  Or even learning how to work with the e-mail based bug and
patch systems used here.

Ah, the irony — I do see a future where I help to implement the global
transformations.  But to realize this future I need to learn more and
complete my development system.  While having a life outside of
computers... :-)
