So they cleverly side-stepped the Boaty issue by picking a name to which people can't object without being accused of picking on a "nice" 90-year-old man. I don't think that's a good basis for a naming policy.
I'm sure there are many publicly-anonymous actual research scientists who could have received this honour instead and BIS / NERC could still have thrown the Boaty-as-ROV bone to the voters.
