Do the copyright holders get to declare what is or is not a derived
work? I would expect that to be a matter of law, not to be defined in
the license terms.

It's explicitly a request, so this doesn't impose an additional
restriction. Good.

Ditto for re-defining the copyright law term “derived work”.

Limiting the scope of the additional permission. Fine.

Imposing an additional restriction on top of what the LGPL requires,
AFAICT. If so, this clause makes the work non-free.

It seems that the above comments also apply to these terms.
