It'll still work. It's a very common notation for link local addresses, since with multiple interfaces you have multiple routes with the exact same prefix (including length). One `fe80::/64 dev ` entry for every ipv6 enabled interface, so things such as `ping fe80::1` don't know what to do, so you need to either add `-I IFACE` or use `fe80::1%IFACE`. `getaddrinfo()` also generally supports it, so any application using it properly will work fine with this. (eg. `ssh foo@fe80::1%eth0` works)
