If I understand, QUIC exists to multiplex multiple streams over the same UDP channel, including same key exchange.
QUIC also has an unreliable transport mode for VoIP, etc. https://datatracker.ietf.org/doc/draft-pauly-quic-datagram/
Has anyone considered a “file" transfer mode for QUIC that uses either this unreliable mode or another "less" reliable mode? Would file transfer benefit much from even less ordered delivery than a QUIC stream supports?
There is a bittorrent variant µTP (BEP-29) which exists partially to interfere less with residential internet, but supports bittorrent's usual highly unordered delivery.
I suppose a file transfer protocol for QUIC could also be bittorren-like by accepting packet sized chunks from multiple senders, but that's another topic.
