15 : - QUIC_VOTE
16 : - QUIC_TPU
17 : - UDP_VOTE
18 : - UDP_TPU
19 :
20 : For the UDP ports, we simply send to that sockaddr when the leader is selected.
21 : For QUIC ports, we establish a quic connection just in time for the leader slot.
22 : We allow that connection to time out if it's going to be dormant for a while.
23 : This reduces the bandwidth consumed and the amount of work the fd_quic needs to do.
