Can we get around this workaround once the gyp deprecation is complete?

Not because of the deprecation. Only by investing more work and e.g.
blacklisting the archive in all infrastructure archiving scripts out there (I
count three). I'll keep that in mind with a lower prio.

+# not in the product directory. Therefore we track running of this script
+# with an extra stamp file in the product directory.
