Where did that discussion happen? All I have heard of was discussions at
PyCon, where nobody quite seemed to see any point in the whole different
request types story at all anymore.

I don't mind if the skinnable story gets less intermingled with the
request story in a new zope.skinnable package and breaks some backwards
compatibility at that point. Right now that mix of the two concepts is
so prevalent in all kinds of places, that I'd rather stay on the
backwards compatible side.

All ZCML browser directives by default register everything for
IDefaultBrowserLayer and expect those resources to be available on
"normal" browser requests. The test helpers in zope.app.testing to get
browser resources set up rely on the same mix of concerns. This stuff is
used all over the place without caring about loading zope.publisher's
ZCML right now.

I call that retaining sensible defaults. You can opt-out of the
IDefaultBrowserLayer for browser requests by providing your own
specialized adapter. I prefer no configuration for the most common case
with an opt-out scenario instead of the everything is opt-in behavior.

zope.publisher is the package that defines the IBrowserRequest
interface. It might make sense to split those concerns off into
different packages and then straighten out the dependencies. At that
point I can see having a setDefaultSkin method inside zope.skinnable
with a different behavior. But the one inside zope.publisher ought to
play nicely with IBrowserRequest.
