If you can not run the test suite, then how do you know that you properly followed the spec? And did so securely? And in a performant manner? Even for edge cases? On obscure hardware, filesystems, and OSes? Even if the power cuts out? Or the cable to the hard drive (transactions)? Even if a stray cosmic ray flips a bit?

By the way, SQLite itself does not meet one of these criteria. Know which one? ))

I’m not sure what your point is? Yes, it would be better if they would run their tests against your fork. But they won’t. Still, it’s better for the fork writer that they exist.
