When should I enable 802.11k, 802.11v, 802.11r?

Does it make sense to enable any of these features on network with single 2.4GHz only AP? Does it (especially 11k) allow for better automatic channel selection and/or bandwidth management, or are these features completely useless in such scenario? Thanks.

Not really (k/ v might still serve 'some' purpose, but in a very limited way with only a single AP and radio).
