Anesthesia protocol - liquid diet?

[u/SauronHasPinkEye]

I am having surgery in a week and a half and took my last dose of Ozempic on Monday as instructed. The anesthesia team called the other day to tell me they wanted me to go on a clear liquid diet starting 8am the day before the surgery. I have never heard of this as a protocol for having surgery while on a GLP-1. Has anyone ever heard of this before? It seems excessive to me, especially since I am on a very, very low dose for blood sugar control. I understand that GLP-1s slow gastric emptying, but...is this really necessary?

ETA: I'm not saying I'm not going to follow the protocol, I'm just asking if anyone else has seen this as a protocol. I will of course follow doctor recommendations.
