Lets hope that new UI for managing the allowed origins gets revamped too as it is too quirky/simplistic as it is right now, actually ever since it was introduced for the first time. I have an extension that has a UI for managing the allowed origins through an options page since 2016, long before we got that sort of UI inside the extension's management page as well. Requesting access to all sites has always been the 'default' unfortunately, either because developers didn't care, Google did not enforce good practices, or users did not care/understand the severity of this permission, or maybe all at the same time .. I think this will limit the third-party tracking services that some developers employ for profit, but I may be wrong about that, though you can always ask for access to all sites and any other permission afterwards.
