Hrm.  So using a package file with LaTeX-Format is not analogous to
linking (i.e., doesn't result in a combined, derived work)?  Have you
confirmed this in any way, or is this your opinion?  Because if there
are GPL'd package files this may be an important issue.  Especially if
any of them incorporate GPL code from other sources.

Ok.  As you say, something can still be free and yet not GPL
compatible.  The only reason this would be a problem is if the GPL's
"viral" properties come into play when used with LaTeX-Format.  To me
(IANAL) this seems likely since a package file is actually rewriting
the base format, as I understand it.  If so it's fairly important that
the LPPL be GPL compatible, or that the GPL'd packages include an
exception allowing "linking" with LPPL stuff.
