Network bridge where all member-VMs are isolated?

I want to create a Linux Bridge where all members will be isolated from each other, and can only reach the gateway.

As far as I've read Proxmox SDN aims to achieve the inverse; however Linux bridges support isolation natively; I have just ran the following commands and observed this leads to isolation for the two attached VMs.

Code:
bridge link set dev fwpr102p0 isolated on
bridge link set dev fwpr100p0 isolated on

Is there any reason this is not an option on a bridge (default) or network interface level? Are there better options that don't lead to having to create tons of seperate bridges or using SDN features such as VXLAN that overly complicate setup?

I am aware that I will have to also perform isolation on switch-level; but I think our L3 switch can handle that perfectly fine.
