I think for PVE 7, we mainly want to provide an easy way to stay
compatible to the old behaviour, that would basically mean:

pveum acl modify /sdn/zones/localnetwork --groups XXX --users YYY --tokens ZZZ --roles PVESDNUser

rinse repeat for any SDN zones if you have any.

for the GUI, the least invasive change would be to just add a hardcoded
ACL selector entry for /sdn/zones/localnetwork (the rest can be done
manually via the GUI or pveum).

note that existing guests continue to work fine, it's just
- creating new ones (from scratch, backup or via clone)
- modifying any virtual nics on any guests

that require the permissions.

PVEAdmins and existing PVESDNAdmins would already have the required
permissions anyway (Administrator as well). so this would mostly affect
PVEVMAdmins and custom roles.
