Bugzilla

I'm wondering how we should be using bugzilla in light of our new project organizational structure.  Do we want to add more "Components" to choose from in bugzilla reflecting, say, the products of the various teams?  There is already a "build system" component, which is great.  What about a "framework" component, representing bugs (and feature requests) expected to be most relevant to the Framework Team? 

And what about bugs reported for various extension modules?  I'm currently working on making the comad implementation of the First Provenance Challenge available to the community as a new module.  As I'm doing this I'm running into things I'd like to change both in that module and in the comad module (some are "bugs", others are "improvements").  How should such "bugs" be categorized in bugzilla?
