I think the main issue here is that it's not walking on water itself that's the problem, but the fact that it's automatically guaranteed by a Devil Fruit power. Neither Brook nor Aokiji have in their powers "can instantly walk on water." They can do that because they're cleverly making the best out of their powers and circumstances. But neither the Yomi Yomi no Mi nor the Hie Hie no Mi state "the user can now walk on water."

Essentially, if a DF lets you walk on water, then you don't need any effort in doing so because you'll always end up floating. But if it's not a power, then the user can still find ways to float by being resourceful with their powers (or with technology, such as using pool floaties or coating from Sabaody.)
