To reflect the snark right back: If you think Safari warrants primary support, ask Apple to provide ways to test in Safari without paying Apple for the privilege.
Microsoft got this one right when they released free Windows VMs for various combinations of Windows and IE versions.
Now, yes, it's fairly likely OP is already using macOS and they just didn't bother testing Safari, but if you want to be snarky about browser testing, be snarky to Apple first. They're intentionally making it difficult to test in Safari.
