[Twisted-Python] Twisted and Component Architecture

Well, since it's been mentioned here, guess I'll step in.
First, I implemented a simplistic system because I needed adapters for
Twisted's config system (it used to use mixin classes *shudder*), so I
quickly wrote up something which implemented them. The fact that
__implements__ checks the class is an implementation artifact - I can
easily change it so it works like Zope3's.
Which brings us to the next issue - should I be using Zope3's CA?
Apparently I can't - Twisted is intended to run on 1.5.2 upwards, and
even we drop 1.5.2 support we will be using 2.1 as the baseline.
Interface packages and CA package are 2.2 only.
So, this is what I think I'll do - I'll refactor the minimum
implementation Twisted's uses, making sure that it uses the same
semantics and syntax as Zope3's (e.g. __implements__ being a
tuple/singelton instead of lists - why was this made inconsistent in
Zope, anyway?). If Zope3 is importable then Zope.CA's implementation
will be used instead.
Any issues anyone can think of in doing this?
