Yep is a big long tail to think about solving for, decades of features / idiosyncrasies in a complex domain.
Indeed it is. We founded Ariga (the company that's maintaining Atlas) to build this kind of infrastructure which we feel is missing from the data infra/platform engineering landscape. Aside from our existing love for open-source (we maintain https://entgo.io), we are building Atlas in the open because we understand the scope of the problem and it's long-tail characteristics and realize that it will have to be a community effort.
