>I'm convinced copyright assignment (CA) is a poor idea in just about all cases
I doubt anyone's even reading this now it's been a few weeks, but I would appreciate it if 'copyright assignment' is *never* shortened to 'CA'.
The reason for this is that 'CA' also stands for 'contributor agreement' (or similar), which is something that can't be distinguished in context, as the context in which you might use either term is essentially the same - and the meaning is similar.
It leads to the two different things being frequently conflated, in precisely the discussions where the difference between them is the most important.
