Doesn't work well. Has security problems (mismatch between reported IP addresses used and actual addresses in use) and it can't reacquire the opposing endpoint if an address is lost before a new one is communicated. MPTCP has been complete for years. The adoption rate is very low. QUIC is better, but it still leaves finding the server's new IP address as an exercise for a process outside of the protocol. I haven't kept my ear to the ground for the last year or two but I haven't heard about it making the expected inroads versus HTTP 1.1 over TCP. Unfortunately, QUIC is a very complex protocol that's very hard to troubleshoot. The complexity comes from a slew of mandatory security components which should have been optional.
