Agree, 

HA cannot and should not guarantee broken switch also works.
Let's forget about HA, in a non-HA setting, if a workstation on LAN changed
a NIC, and reboot (to send gratuitous ARP), the switch should timely
capture this mapping (instead of until cache timeout). 

If this basic need cannot met, the switch should be
replaced even when we have no HA.

(But we should mention the broke switch issue in installtion manual).
