Edge functions Websocket support?

I'm on the fence with using Supabase but stuck on one thing missing; I need to use Websockets and would love to use Edge functions to do it.
I understand the reasons for the POST only restriction, however it prevents Connection: Upgrade as only GET is supported https://www.rfc-editor.org/rfc/rfc6455#page-17.
Are there any plans to relax the restrictions to allow Websocket connections, or is this already supported and I'm unaware?
