You wouldn't use VRRP in these cases these days - since the networking world has moved on and now L3 is generally pushed to ToRs, you would use BGP to announce a /32 or /128 and configure an ECMP group on the ToR. This gives you not only redundancy then, but also traffic splitting. Maglev does use BGP, too (although in a way indirectly due to scale reasons).

Just because a customer has access to L2 fabric via a VLAN between customer's hardware does not mean the customer has access to be able to tweak ToR switch configuration.

Using BGP on a L2 vlan for handling a single digit number of IP addresses allocated to the entry points is akin to using K8S to host a static HTML page.

Right, but if they're using k8s, they better already have support from their local network operations team.
