I am not sure they get it all, but they can serve as a start.

If it is a mere aggregate, surely there would be no resulting copyright. If

***beyond what the individual works permit***
I think this is the weak phrase here.
Make an aggregate of lots of Free works and several ARR works. The ARR work(s)
allow(s) restricting the compilation.
In my thinking, surely something that is merely an aggregate does not deserve
copyright protection and so my thinking would not kick in. But, if copyright
law gives the aggregate/compilation/collection copyright protection then the
law thinks it is more than mere aggregation and so my thinking / proposal
would kick in.
It would then be creative aggregation and not mere aggregation in my books. If
you get a copyright on the aggregate, obey the Free dictates on the Free
copyleft licenses of the parts.

Their thinking may be ok, I think the language is flawed enough to want a fix
before allowing for a one way BY-SA -> GPL conversion.

What I propose for BY-SA would not make the other parts be BY-SA, it would
just require that they be Free. And that the umbrella copyright be BY-SA if
possible, other copyleft Free second preference, and permissive Free as a
last resort. Non-Free not allowed.
Would Debian really consider it non-Free to forbid non-Freedom?

In my thinking, a true mere aggregate could not get a copyright and therefore
Free and non-Free could be mixed.
Do we need to prevent that mixing unless is at arms length from the non-Free

There is no contamination contemplated. Just an unwillingness to be grouped
along with non-Free stuff under an umbrella copyright.

And I think the GPL wording wording is flawed and will not do what I think it
is trying to do.
