Moving ITerms to zope.schema, even if we skip the request as 
adapter discrimintator, can offer support for your 20% or 1%.
This let us implement ITerm or title tokenized term adapter
based on a standard ITerms interface for ISource.

I'm not 100% sure, but it looks to me that if you use
zc.sourcefactory every ISource implementation from you
will 100% depend on ITerms if it comes to widgets, doesn't 
matter if you use title token term or what ever. You don't 
have to implement that part because zc.sourcefactory does 
it for you.

Can you agree that every ISource implementation based on
zc.sourcefactory depends on ITerms from zope.app.form.

Take a look at MappedTerms in zc.sourcefactory.browser.mapping.
I guess this mapping is used for any zc.resourcefactory
implementation. right?
I'm not sure because I don't use that package right now.
