Hi Piotr
When you tie static routes with BFD like this:
ip static <source> <destination> fall-over bfd
You're literally making static route dependant on BFD status which means if BFD session goes down or even if you force it administratively down, your static route is removed from routing table so you can't really say it does nothing, can you?
BTW, this is how it's used in real life (for redundancy).
Maybe I didn't quite understand your question but multiple next hop for single Floating IP is usually achieved by using VRRP protocol. BFD creates a session for end-points already 'reachable'.
