To a certain extent, yes.
However, the core issue is whether anyone who uses the symbol
is creating a derivative work. If it is pretty clear that this
is the case, you really should mark the exported symbols GPL.
In my opinion, in this case it is pretty clear that any use of
these new symbols would be a derivative work and therefore they
all should be marked GPL.
