@fnando, why this brilliant pr is not merged yet?
in my case, i have ar-MA and ar that backs it up. so, my available locales include ar - else fallback is not working. but i dont need to check ar.* with lint. being able to ignore patterns in lint would be awesome, because i will never add 4k+ keys to ignore config.
