I think that's an important catch, flow breaking can happen dependent on what hardware you're using and how you swap in next-hops. It definitely requires a deep understanding of how flows are hashed.

Agreed. Also many applications for this you might just not care if a flow gets broken. Really depends on your use case.

Persistent hashing is key if you care about it though, I honestly don't know which routers do this off the top of my head :)
