It doesn't use forwarders.  There was a stub zone that used forwarders
for the .de DNSSEC testbed, like this:

    http://www.denic.de/fileadmin/public/events/DNSSEC_testbed/dnssec-testbed-muster-bind.txt

But it's now been replaced by the new (in 9.8.0) static-stub zone:

    http://www.denic.de/fileadmin/public/events/DNSSEC_testbed/dnssec-testbed-muster-bind98.txt

I briefly commented out this zone to see whether it made any difference
wrt the wildcard NSEC RR for *.cw.test.itec-usa.com, and it didn't.
