I see that zope.component now relies fairly heavily on the setuptools
"extras_require", which makes the proposed move possible. At what point
did we decide extras_require is good? Just curious.

I think it was grandfathered in.

We didn't. This extras_requires has been in there for a long time, as
the other ZCML statements are already defined in it.

In the past I proposed pulling out the ZCML statement implementations
from zope.component into something like zope.componentzcml, or
zcml.component or whatnot. That could still happen, if we can find some
consensus.

Regards,

Martijn

All right, thanks for trying. Hopefully someone else can take a look at
it at some point.

With the recent changes zope.app.component is almost devoid of code and
packages that relied on zope.app.component now can rely on other
packages and entirely avoid the zope.formlib dependency.

zope.app.exception only depended on formlib's namedtemplate facility
which now resides in zope.app.pagetemplate instead.

zope.app.zcmlfiles is a scary package that just pulls in a lot of ZCML
that hopefully can vanish entirely over time.

Martijn
