I see two uses of this interface, both in combination with `Interpolatable`.  Should this just extend `Interpolatable`, or are there cases to be expected where this marker is present but `Interpolatable` is not?

Also, have you considered adding a default method to `Interpolatable` to indicate it supports component wise interpolation?

It looks modelled after `RandomAccess`, but the reasons for that being a marker interface are not similar to this situation (it is a marker interface so it can also mark the old collections, like `Vector`).
