Ok, I will relent on allow `linalg.copy` be handled special case, though i'd strongly prefer not special casing `linalg.copy` this way. We should really just be collapsing on `linalg.generic` and "matching" back to `linalg.copy` if needed. But that might be a preference, so this path is OK.

Please do remove the `static_asserts` though... they cause deployment issues downstream.
