I can't talk for every user but I find these dots annoying for things that don't requires my immediate attention. As an example, It is like the red dot on Edge to use a Microsoft account, the dot is placed there because a lot of people will get annoyed and just make an account to get rid of it.
As I explained on the original report, If I switch the manifest to version 2, there is no request for permissions at install time, no blue dot on every site and even I can access protected information like
If the blue dot was important, it should have been important on V2 manifest too.
As a side note, a V3 extension with only optional permissions:
In order to request permissions for each site if needed at runtime, shows the blue dot for every site. The idea of them being optional is that the extension can do some operation without these permissions and later ask for them if required.
