BTW, at what point (and in what forum) was this design decision made?

I can see the advantages of this decision the more I think about it, but
the inconsistency with DTMLFile still bothers me, as it erects another
barrier to migration of developers from DTML to TAL (at least for
products). In return, we get greater convenience for skinning, but I'm
not sure the tradeoff was worth it.
