`Differentiable` requres `Equatable` AND `Hashable`, but docs say otherwise

Expected Behavior

The docs (README) specifies that:

There are default implementations of Differentiable for the types that conforming to Equatable [or] Hashable

Current Behavior

Differentiable is defined as such:

public typealias Differentiable = ContentIdentifiable & ContentEquatable

Detailed Description (Include Screenshots)

This discrepancy cost me a few days of refactoring, due to having many nested types that aren't all Equatable or Hashable. I conformed them to Equatable, and theoretically they should be Differentiable, but they don't seem to be. Any advice or workarounds appreciated here, but, this seems like a difference between the docs + code.
