While I would push people towards epp check, having domain availability in an anycasted zone for DNS queries is so much more lightweight.
We did this in .cc back in 1998 The registry loses the ability to measure which domains are getting looked up or measure volumes accurately, but registrars already use zonefiles or cached results and look to alternatives to epp check to speed the process of responding to customers in order to not lose sales, so that data on checks is not 100% no matter what. Check commands are read-only, so this increases resilience and speed.
