The views don't know. Views are multi-adapters to context and layer.
grok.View is registered to IDefaultBrowserLayer, mars.layer checks class
or module directive for a layer to register to (defaulting to
IDefaultBrowserLayer).

mars.layer is identical to Kevin's layer branch IIRC. I'm suprised
no-one has had a need for it.

I think you may have mentioned something like that and though I began
working in a branch it felt best to be apart. I named the namespace mars
for obvious reasons. "Working from mars" (thanks Kevin).

I found that when I was in the swing of tfws.website I quickly become
comfortable configuring the components without touching a zcml file. I'm
looking forward to getting back to it.

I would need more time to attempt that. I hope that I shall do in the
near future.

I think that mars reintroduces configuration back into the picture that
doesn't sit well with the convention over configuration mantra. Most of
mars came to being to reproduce z3c.formdemo so it naturally follows
presentation patterns developed by the z3c crew. Bless their talented
hearts. I trust their work and I continue to be comfortable with the
solutions they have come up with. (Historically the first 3rd party
packages I played with were the `tiks` packages).

Kevin's layer branch should definitely find its way into the core.

Best regards,
Darryl
