No, not really important. Regardless, the definition of "derived" product,

In the GPL, "mere aggregation" is clearly set out as non-infringing.

usually, but check out
"Can I apply the GPL when writing a plug-in for a non-free program?"
"If the program uses fork and exec to invoke plug-ins, then the plug-ins
are separate programs, so the license for the main program makes no
requirements for them. So you can use the GPL for a plug-in, and there are
no special requirements."
"If the program dynamically links plug-ins, and they make function calls
to each other and share data structures, we believe they form a single
program, which must be treated as an extension of both the main program
and the plug-ins. This means that combination of the GPL-covered plug-in
with the non-free main program would violate the GPL. However, you can
resolve that legal problem by adding an exception to your plug-in's
license, giving permission to link it with the non-free main program."
