Using allowType I can whitelist all contentTypes I want to show in the content selector list.
But that means whenever a new contentType comes along that I want listed, I have to go through all parts, etc with content selectors and add the new contentType.
I’d rather have a blacklist to deny the few pesky contentTypes I do not want to show. Like the 2K postoffices.
Similary I’m guessing blacklist on path could work to.
