Is there a use case of static routes combined with FHRP south bound?

Here is a simple topology. Will this make sense? What could even be the use case?

​

The R1 and R2 are running HSRP or VRRP pair with VIP as 192.168.0.1 and R1 as the active gateway with R2 as standby. The PC1&2 have default gateway to 192.168.0.1 and 172.16.7.1 respectively and both R1&R2 are default route to 1.1.1.1 on WAN router. The WAN router has two equal cost static routes for subnet 192.168.0.0/24 via 1.1.1.2 and 1.1.1.3.

​

So if R1&R2 were running dynamic routing protocols with WAN router, the topology would make sense from redundancy/failover perspective...but with static routes everywhere, what could be the benefits of using FHRP then?

​

Here are failure scenarios from what I can tell:

1. The R1 is the active gateway for 192.168.0.0/24 subnet. Somehow R1 port eth0/1 is down...PC2 would lose connectivity to PC1, vice versa; (even with track sla on WAN router for the static routes...)
2. The R1 is the active gateway for 192.168.0.0/24 subnet. Somehow R1 port eth0/0 is down OR R1 is down, communication between two PCs would failover to R2;
3. The R1 is the active gateway for 192.168.0.0/24 subnet. Somehow R2 port eth0/0 is down OR R2 is down, there should not be any communication impact between the two PCs.
