Can we declare package-includes to be bad in general than and abandon it
please? At least tell everyone not to use it if possible?

The 'package-includes' mechanism is set up in a normal instance that
site-zcml does not load *-ftesting.zcml slugs, whereas ftesting.zcml
does includes *-ftesting.zcml slugs, so you can 'safely' place your
ftesting configuration there.

Ah. I didn't make the connection in my brain to make the test runner
change the working directory. That sounds reasonable right now.

Ah. I forgot to use zc.sharing as a buildout example.

Thanks,
