UDP (which WireGuard uses to encapsulate your data) traffic is often de-prioritized. You won't notice it when the network load is low, but it will seriously degrade experience during high load periods.

Wouldn't deprioritizing interfere with regular web traffic these days, given that close to one third of non-bot traffic reported by Cloudflare is over UDP with HTTP/3[0]?

I'd certainly hope ISP follow your reasoning. BTW that was why I put my WireGuard server on port 443, hoping it would avoid the tragic QoS…
