If I extend a salesprocess and want to show my field on every card and list page, I will need many Page Extensions and so I will need a huge ID Range only for page Extensions.
Since I can only have 1 "page extension object" for a page inside my module it would be enough for business central to know that a page extension is related to my app-guid.
I agree table extensions and page extensions will be capped at a certain point when you have enough volume of apps using the same objects as dependencies.
Same goes with table extensions I would say.
