Ok, that took 30 minutes out of my day :-)

I saw something similar, probably it was that file. I don't remember
seeing that "remove" option used a lot, perhaps I should investigating
that one a bit in the profiles in which I thought something was
missing.

Ok, so they're all optional directives. That's what I wondered about.
I didn't expect every insert-before to work, but I was surprised to
see an XML format error once I put a "purge" inside a profile that
didn't support it :-)

Yep, make it easy to add genericsetup to your product and you've
solved 3/4 of the problem :-)
