Very close, if you get rid of the current requirement to explicitly
specify "allow" (which I don't like anyway)

I'll grant the extensibility win, but it's LESS compact than what we
have now due to the required braces, brackets, and quoting. It's a
clear lose on legibility but that may be somewhat compensated for by
making it easy for tools to parse and write.
