That’s the same I see on my Mojave systems. And that’s bad for two reasons:
It indicates there’s something to act on, but you know not really. So you learn to ignore those badges. Not a thing we want to learn.
When there’s an actually important update you’d want, such as a security update, you won’t notice because all you’ll ever see is that one badge you’ve learned to ignore.
Can we get used to nuisance badges? Yes. Do we want to or should we want to? No. The proper fix is for Apple to reintroduce a “yes I know, now ignore” option. Just like they used to. It’s really not rocket science.
