Apple Watch message deletion

How do you contact the Apple Watch development team so that something gets added to their change log? The fact that deleted messages via the iPhone are not sync'd with the watch is surprising. Found this response on some forum that makes me think this is the case.

"While message delivery is synced between the Apple Watch and an iPhone, message deletion is not. Therefore, users will need to manually delete messages on the Apple Watch, regardless of whether they have been deleted from the iPhone or not."
