For Hong Kong, if the creation of the new political norm is that the populace and politicians will gradually come to understand and respect the Chinese government's red lines and recognize that loyalty to the central government and respect of its political and geopolitical concerns are a prerequisite for a political career, then I think that is something many here would welcome.
After all, that way it would achieve the goal that Hong Kong is not allowed to achieve more political autonomy than what the central government is willing to bestow, while simultaneously meaning Hong Kong will not become an enclave of foreign supported political activity that can challenge the central government.
That sounds awfully like the CCP getting its way without having to make any real concessions, other than perhaps hollow Chief Executive "elections" where any candidate the CCP doesn't like is disqualified from running.
Recent news supports this view. It wasn't enough for the disqualified candidates/lawmakers to say they wouldn't engage again in the behaviour the HK government criticised them for in their registration letters. In fact, I think they were all disqualified. It seems that the only reason the letters were sent at all was because previously the HK courts said they needed to give candidates the "opportunity" to address concerns before they were disqualified. So they pretended to give the opportunity to the candidates to run for election to avoid another loss in court.
Saying that HK politicians have to be "loyal" to the central government realistically means they have to do what the central government wants. Loyalty for the CCP isn't an issue of technically showing respect, it's about subservience. Even within the CCP you're not allowed to criticise Xi, and there's no reason to believe that will get any better soon. Right, now, the central government doesn't want any change in HK, even if that means stagnation and declining living standards.
We're also in the curious situation where the HK government (maybe or maybe not poked by the CCP) has said that voting against government policy/budgets is a breach of the law, in which case why bother having LegCo at all if it's to be a rubber-stamp legislative.
Trust is usually earned rather than given as an obligation. Right now the CCP is not doing a lot to make HKers trust them. I appreciate that you're wishing for a better future, but as I think most HKers see it they're being forced into submission rather than being reasons for them to choose go along with what the CCP wants.
The goal is to achieve a Hong Kong which is peaceful, with greater economic integration with the mainland
On a side note, I'm not sure that greater economic integration with the mainland is necessarily a good thing for Hong Kong. If it's to remain a special place it needs to have diverse trade links. If it is fully integrated with the mainland then it just becomes another Chinese city, and quite probably a poor relation to Shenzhen.
