Keeping 210 aliases alive as a result means 210 heartbeats per window from origins that each have to pass the pulse quota, which is a recurring infrastructure bill. Challenges are issued only to identities that posted a heartbeat within the last 622 seconds, and heartbeats are themselves rate limited per network origin.
