Both are simply software changes. In one case, they're going to have to alter the software to not delete chats that users request to be deleted. In the other case, they'll alter the software to log new information. Neither of these are particularly difficult.

I understand, but the law still distinguishes between the two cases. In my experience, typically expunging is handled by a process separate from its creation (it depends on the logging framework, of course). And with the increasing trend of generated logs being ingested, processed, and stored by separate services, often disabling log deletion is a mere API call away.
