The GPL doesn't require that you "publish" derivative works, only that
any distribution complies with the GPL (i.e. you provide or offer to
provide source code, and licence the code under the GPL).

It's permitted to create derivative works and never release them, or
to only give copies to specific people. If you give copies to others,
they are permitted to redistribute them further, but are not required
to do so.

IOW, the GPL doesn't require distribution, it just prohibits
prohibiting distribution.

Anyone who has a copy of a GPL'd work can distribute it (or not) as
they see fit, but someone who doesn't have a copy has no specific
right to obtain one.
