Cool.  I'll comment, and then post a separate message about some things
I'd like to see in ZConfig.  (Fred created a wiki on zope.org but wikis
were broken there and I don't know if they've been fixed.)

FTR, of course I'm using ZConfig in various Zope projects that I work
on, but I'm also going to be using ZConfig in Mailman 3.

This is how I'm using extended section types in my code currently.  The
proposed change won't affect me because I explicitly specify the data
types in derived section types.  It seems to me unlikely that you'd have
a base section type with a non-default data type, with derived section
types that rely on the default data type.
