GNU faq isn't a real source; jurisprudence and the license itself is. And there isn't much jurisprudence about what derivate work is (within a plugin system). Even SFLC doesn't know this for sure (while they surely have a strong opinion). Given GNU-faq, the Wordpress case and the way Kodi works with addons, all addons should be GPL except for images. Good luck to the future judge to find a definition of derivative work in a plugin system ;-)
I don't think a judge will care about all the techno mumble; he will only care which party to blame, either plugin or main program (remember the facilitating argument which is used a lot in p2p-cases?). The question whether a plugin needs to adopt GPL is only relevant for some OSS licenses.
But this discussion is drifting towards a GPL-discussion. To answer OP question:
No it's not really possible to protect Python scripts besides the options topfs2 listed.
