IIRC, we don't have any immediate plans for it.

All the requests we have seen have mainly been for Supabase, and Supabase also provides IPv4, so this request, admittedly, doesn't rank that high on our end.

Ok, Supabase only provides it at a minimum $29 point. AWS started charging for ipv4 addresses 2 years ago, I suspect this request will become more common
