Reverse option for condition

[bjarnef]

For a specific use case I have a custom condition to check for access and in that case need to make some properties read-only.
However I noticed when permitted in condition in true the extension executes (in this case workspaceContext), otherwise it didn't initialize the following.

While I can reverse the condition, I think it may be useful having a negate and/or revese option (similar to in IIS redirects).
E.g. instead of match specific content type(s) using match or oneOf, it could match any besides specific matches.
