I'm not sure I understand. DPs aren't tied to any location - they are all itty-bitty portions of the overall Trust. (Which I know you know...I just don't understand what you are getting at).
I more see DVC following in MVCI's footsteps. When MVCI announced the DP program I assumed (as did many others) that it would be like HGVC where points were immutably tied to weeks and 'points in equals points out'. HA! Instead MVCI created an money making machine. By stripping resale weeks of their DP value and heavily 'taxing' resale DPs, MVCI drove down the price of resale weeks and points thus allowing them to buy them cheaply and then resell them for full price. "ROFR then resale" is much more profitable than "Develop and sell".
Years before Marriott's points system was implemented the rumors were all over the place and many of us were hopeful that it wouldn't be a completely separate system from existing Weeks, that it would provide some kind of internal exchange opportunity for those Weeks. I was among those who wanted that but fully expected it to come at a price, because why else would Marriott do it and II certainly comes at a price. The metric we use to determine whether there's value in enrolling Weeks is how our particular ownership exchange value in the DC compares to that from II, and for many of us Marriott's DC comes out ahead.
As for resale values and ROFR opportunities, Marriott had never guaranteed that they'd always exercise ROFR and thus prop up resale values, and they'd never prioritized protecting any resale values for owners over their bottom line. No doubt the DC introduction has had some impact on resale values but the primary reason it was introduced was because the Weeks system wasn't going to be sustainable forever, not with new development costs skyrocketing and low-usage-value unsold Weeks at existing resorts being a constant drag on Marriott. It sure didn't help that the years-long-rumored Marriott point system was coincidentally implemented during an economic downturn.
DVC will now be able to do this with Riviera, Reflections, the other resorts they build before 2042, and then as contracts mature and get reissued with new language all the 'original 14' as well.
The comparison I'm making between what DVC will now apparently be doing and what
some Marriott sales reps have been claiming will be done but which isn't being done yet (although it's allowable based on the DC gov docs,) is restricting exchanges by resale owners among only certain resorts. Until now any resale DVC owners have been allowed to exchange throughout the entire system based on how many Points are owned and how many it costs for specific stays, with only home/away resort reservation windows and availability restrictions, so I'd say this new thing is certainly a drastic change.
Marriott DC members/owners deal with similar owned Points/reservation window/Points Chart requirements/availability restrictions. But since the Marriott DC inception the constant nonexistent threat is that any new properties brought onboard (whether ground-up development or via licensing) would be restricted to only those who purchased already-enrolled Weeks direct or Trust Points direct, or, only those who purchase Trust Points direct after the property is brought onboard. That hasn't been the case with any new properties but if/when Marriott implements any of these or any other resort-specific restrictions, I'll call that a drastic change, too. For now and hopefully continuing (although DVC's inroads here aren't a good harbinger) it's just something to think about and not something to deal with.
