hoes will complain about numeronyms like a11y and then use garbage like /lh and /genq if you think your writing is ambiguous then use more words, I promise no one will complain about the wasted bytes
the point here is that it's not less accessible than any other acronym as it's well known and easy to remember, unless you tell me screen readers don't play well with the numeral in the middle of it or something (which I doubt but hey that's not impossible)
