alt Hacker NewsEh, every term for disabled people becomes a slur. Moron->idiot->retard (the latter being so unacceptable in modern speech it is labelled by the kids as "the hard r"). But you are right, we should simply not use terms for disabled people in software names. I propose "Thirty Years and Still Cannot Draw a Circle" or the hip short name :no-entry-sign: emoji.
Tangent, but it might help you avoid an embarrassing situation later on. If someone says "They called me the hard-R", they're not talking about the R-word.
"R----d" is usually just called "the R word", while "the hard R" refers specifically to the standard version of "the N word". (As opposed to "the soft A", which is sometimes used synonymous with "dude".)
