Looking Beyond the shitty title that doesn’t tell you why it’s “unique” until you click the link (and it is not unique anyway), I can’t imagine this tool will provide consistent value for a user. Sure, every now and then, you’ll want to trace back relationships strictly defined by a user at some point… but what meaningful business use cases are there?

The use cases are right there in the first section. You're being a dick to the authors just because you don't understand why this is useful. Please take a moment and chill.

The tool is aimed more at developers/quality assurance specialists. So people who have a more technical view of the data. It is therefore not much about business cases.

Furthermore, the relationships do not have to be defined manually either. Rather, they are automatically recognized based on the database metadata. (However, manual entry is also possible).

Moreover, it is not just a "tool", but "tools". In addition to the data browser that you are talking about here, there is also the "subsetter" (for extracting consistent subsets of a database). And for sure this tool is unique.
