[squeak-dev] Should you override #doesNotUnderstand: and #respondsTo: together?

Hi all,
just struggled over the fact that Json objects provide access to their keys via #doesNotUnderstand:, but they do not override #respondsTo:. Example:
json := Json readFromString: '{"foo": 42}'.
json foo. "42"
json respondsTo: #foo. "false"
Question: Is this discrepancy indeed desired behavior? Or should we rather always try to override #doesNotUnderstand: and #respondsTo: together?
Best,
Christoph
