Now I've even placed a bounty on Package installer: show all permissions – and still not a single answer. Was the bounty too low, or is there really no answer to the issue? If I just need dote it higher, I'd do so – but I don't want to throw rep to the trash bin ;)

@Izzy I think you'd have to replace the package manager completely to change it

@DanHulme Afaid of that, yes. Was hoping for some Xposed or Magisk module I might have missed.
