Generally it's preferrable to have a test case for all bugs where it's

In your particular PR, it's unlikely that someone will intentionally add
memcpy() back. But it's possible that lines around this memcpy would be
modified in one of the earlier branches, and during the merge git would
automerge by restoring memcpy(). Or that a person resolving the merge
conflict would restore the memcpy() without realizing the consequences.

So, yes, test case is better than no test case.

Sometimes a test case is extremely complex or just impossible to create.
So it's generally at the discretion of the reviewer.

But in this case you're saying that this will be tested in the
versioning.partition test. Perhaps you can simply push it together with
versioning.partition test instead of pushing it separately?
