• HRMP channels let parachains talk to each other.
• Right now, 1000 messages can wait in a line on the relay chain.
• This proposal wants to make the line shorter—only 25 messages.
• Shorter lines help keep the relay chain from getting too busy.
• If a parachain is slow, fewer waiting messages means less work later.
• Only new channels will have the shorter line; old ones stay the same.
• If needed, parachains can ask for a longer line.
