Thanks for the feedback!
I basically was at the same point staring at the screen for a while...
the setting is per VNet (a.k.a. at least for simple/VLAN zones)
bridge-wide - so short of manually fiddling with the port-settings with
`bridge link set` there currently are no such guests AFAICT.
if we adapt it I'd suggest:
This means guests can only send traffic to non-isolated bridge-ports,
which is the bridge itself.
