Depends on the people. At work, we're using Spring (which, as far as 
Java goes, is great). The notion of having XML-based configuration gives 
a lot of wins in certain types of applications - mostly around being 
able to override "deployment" type settings in a staging or developer 
environment.

In any case, I definitely see a case for both. I can't see a good reason 
why we can't have support for simple XML-based component registration 
without having to depend on the ZODB and tons of other Zope eggs.

I understand the historical reasons behind these dependencies, but I 
genuinely think we should pick a few libraries that are "useful" to the 
outside world (zope.interface, zope.component, zope.configuration, 
zope.annotation, zope.event come to mind) and work to make these have 
"clean" dependencies. We don't have to do it all at once, just try to 
identify where there is a need (to me - using basic CA functions, 
including externalised configuration). We should also market this, just 
like Lennart did with his recent blog post (thanks Lennart!)

Otherwise, they are not usable outside "Zope-the-megaframework", in 
which case, why are we doing all this eggification and attempting to 
share the love? :)
