Unclear which restrictions were removed/changed from the original

[allo-]

When I upgrade XPL-EX to the newest I get a notification that a lot of rules from the original were removed to save you headaches. The new rules looks quite a bit different and some permissions that the old rules can remove seem to be not longer supported?

I understand if you don't want to maintain older rules from the app before you forked it, but its hard to tell what the new XPL-EX is still willing to do and what not. Could maybe a FAQ be added explaining the differences of the rules?

The project page claims that you can protect the fingerprintable data better than GrapheneOS (great!), but when I shortly upgraded my impression was that now mostly things like Android-ID were protected (basically the "read identifiers" permission?), but permissions like "read calender data" or "use tracking" and "use analytics" were removed.

Is the new goal that the frameworks are allowed to run but can only read fake data or how can I understand the revised ruleset?

EDIT:
I used the latest tagged release which is still 1.4.x. How do things look regarding this in 1.5.x? Should I rather upgrade to the beta?
