.xdx vs Catalina

I assume there’s no notarization requirement for plugins in Catalina, since XD is doing all the loading, etc? (For development plugins as well.)

But wanted to double-check.

Correct. Notarization does not impact XDX installation.

Of course, this does bring up the subject once again of some kind of “notarization” or “sealing” for Xd plugin-manager-installed plugins, so their source can’t be tampered with.

This is a pretty serious requirement if plugins implement any kind of licensing scheme on their own. If they can’t trust that the sources haven’t been hacked, then all bets are off.
