> @ad-l How does this help? Can't the exporter MS derived at the same time as the traffic secrets?

Sorry, for some reason I was convinced that exporter master includes client finished, but after double checking, this is only the case of resumption master (honestly I think this is wrong because exporter are used for binding authentication and they pretty much fail at binding client authentication. I would suggest this is fixed in future TLS).
