Kudos to the QUIC working group for this absolutely correct response: "We won’t hold any further interim meetings in the US, until there’s a change in this situation."
Then again, needing to put my laptop in check-in luggage (with a backdoored lock? Is that really a thing? I only saw "TSA-approved locks" mentioned somewhere and am only inferring the existence of backdoored locks here) is a no-go in the first place, so I'd need to (1) want to go to the USA, (2) not take a laptop and (3) probably buy a special backdoored suitcase. That's a pretty rare combination.
