We created some permission sets to include with our managed package. However, we have now realized that it isn't the best approach since not all orgs can use permission sets.
However, we cannot find anyway to removed the permission sets from the package...is this possible? There doesn't seem to be any option available from within the create -> package UI or the manager users -> permission sets UI.
EDIT: You have an option to delete the Perm Set on the Perm Set page. However, since this is part of the package (I think). You get this error:
Cannot delete last list view. You can't delete the last list view that's Visible to all users or Visible to certain groups of users.
