That's a nice trick to get a fresh Google Account without any verifications!

But why would you need so many Google accounts? I think at one point it may simply become cumbersome to keep track of all the accounts, so, using an account-less Aurora Store seems like a very easy pathway to take.

I honestly never feel disadvantaged in any way by not having a Google Account on my Android. Aurora Store works, Google Maps works, banking and streaming works, everything just works.

When something important requires a Google account, now you have a burner account you can use. If you somehow have so many you can't keep track of them then great, you can use one account for one thing. If you only have two or three, at least you can make correlating them harder - the perfect's the enemy of the good. (I expect that if you log into more than one on the same Google phone, Google internally marks them as related. Still, other apps don't have access to that fact.)

I usually expressly don't login into any account because I simply don't want to remember which device I've logged which accounts in. It's just easier that way.

On my main device, I'd use a regular Google Account. But if I'm getting a test device, or a device I simply play around with, it doesn't have to have a Google Account, and yet it can still have all the apps I'd ever want.

Unlike with iOS, where you're severely limited in trying out a device without having an Apple Account. Yet somehow it's Apple that's deemed to respect people's privacy, go figure.
