As Hakka language has 3 written scripts, we need to have Hakka translations separated/split into Simplified Han script (hak-hans), Traditional Han script (hak-hant) and Latin script (hak-latn)
After that, the existing translations on translatewiki should be moved to appropriate codes, and there should be no more pages that end in /hak.
And after that, hak should be disabled ("This language code should remain unused. Localise in hak-hans, hak-hant or hak-latn please.").
