I hope no one takes this as an attempt at refuting or denigrating tradition, but I think that the Ramsfoot designation is a good thing.
The vast majority of definitions of a sheepfoot I've seen (actually I don't remember any that didn't, but I try not to use absolutes) have mentioned the spine being parallel with the edge. So yes, this blade shape is not a new design and it's been called a sheepfoot traditionally, but if a more discrete name can be used for this specific type of sheepfoot where the spine has an upward angle in relation to the edge I think it's a good development. It adds clarity without detracting from the traditionality of the design.
But again, I'm no expert and not trying to ruffle any feathers.
