Give an inch and they'll take a mile. The slippery slope is a very valid concern with one of the most powerful potential adversaries actively wanting to integrate you and dismantle your system of government.

From their perspective it's not hard to imagine China trumping up charges (or getting one of the other listed nations to do it) to get their hands on someone they want. Likewise, having the law on the books at all makes it a (comparatively) very small step to simply add more things to the list of acceptable extradition reasons.

China's domestic actions have not given HKers much reason to trust them, and they know that they won't have any chance of clawing back any measure of sovereignty in their system that they give up now.
