In general, for the most part, it looks like the permissions shown higher in the list are the more dangerous ones. In particular, "read and change all your data on websites" is by far the most dangerous permission, and it always appears first or second. ("Access the page debugger backend", which is above it, sounds technical and opaque to most users, but the permission that it gates also triggers the "read and change all your data" warning.) I vaguely suspect that this is by design.
There are several below the fold that I’d consider more dangerous than “show notifications”, but I suppose that one is enough of a nuisance to most people that it gets sorted up. Either way, having this kind of design is an opportunity for it to be gamed. Probably a better design would be more annoying over time (prompting for permissions as needed), but I’m the oddball who’d prefer that annoyance over this kind of approve-and-forget scheme.
Every ad blocker asks for "read and change all your data on websites" permission, same as page scrapers/readability tools - so depending on the disguise I think it won't be hard to get this permission.
