I understand and mostly agree with what you are saying.

The only strong opinion I have is about cbc.twist. Not to be difficult,
but I genuinely feel its goals---being a test-bed to learn and educate
others about mechanics---are best served if any further projects built
upon it are developed in an open fashion. To enforce this, I would like
it to remain GPL.

I think the easiest solution here is that I split cbc.twist from
cbc.solve. This allows the rest of cbc.solve to then be an LGPL FEniCS
App, and I have no other qualms about signing the license change forms.
