Review Comment:
Can you please add some comments explaining the rationale for why this is a
custom derivation for future readers?
Something ilke "Need custom partialEq implementation as field_ids may differ
if metadata is different"

Review Comment:
👍
We can probably add a fast path for the case when the metadata is actually
the same and then we can just compare the field ids
But that could also be done in a different PR
