Yeah, I remember when the "big discussion" about that happened, which revolved around empty themes for page builders.

I actually see this theme as different. It technically supports [almost] everything from WordPress out of the box because it is a child theme of Seedlet. It will absolutely work that way and doesn't require any third-party plugin integrations. However, it does not support comments, so that is at least one strike against it based on the guidelines.

The big thing that it does is give the user the option to disable the title and tagline. And, it provides several block patterns for building out a full page.

The Themes Team has been more lax as of late when it comes to experimental themes related to the block system though, which I think is a good thing. It probably wouldn't hurt to revisit its original stance on blank themes altogether.
