Sure.

Good point. I have been planning to make layers a bit more formal. In
fact, there's a collector item to require layer declaration. This will
happen as part of the refactoring. I've updated the proposal to include
this.

Layers do.  Macros (and slots) are internal to ZPT.  OTOH, I'm sure that
there's room for giving better support for macros. This will require
some creativity and hard thinking. I don't have bandwidth for this myself.
If someone had good ideas *and was willing to take the time to owrk them out*,
I'd be very open to them.  I'm sure there are improvements that could be made
here.
