I'm also now having some issues with whitelisting, any packages which have morph features, such as Skynet's better bends / orifice dynamics, are not working correctly.
Do we need to include folder paths within addonpackages?
"comma- or semicolon-separated exact package-group names" - feels a little vague without an example.
Edit : Just wasted the last half hour of my life.

I've tried every possible combination to get the whitelist working, and I'm out of ideas.
Still these two plugins are not working, haven't tested with others yet.
