I picking this up, because it was also mentioned in a sibling comment. Let's continue this discussion.

It doesn't matter if we have multiple alternative to SBT, some more usable than other. Rust has one package manager (+build tool +distribution tool): Cargo. That's it. Whatever the project you just cloned and whatever the platform you're using, `cargo build` is going to compile it. Now, if every Scala project starts using a different package manager, that's going to be a problem. The best solution would have been to make SBT usable without a prescription from your doctor. It didn't happen. That's okay, programming languages are just tools anyway, and they get replaced too.
