It is an oddly specific choice to use the word macaroon for this, given the widespread confusion over macaron vs. macaroon and how many other unambiguous variants of "cookie" are available for naming a piece of software that is a newer fancier cookie. I do not accept Wikipedia's milquetoast concession to call a macaron a "French macaroon".

Was it intentionally named as an allusion to this confusion? Software is full of hand-wringing over naming and the importance of naming. Is it supposed to be a kind of cookie that is often mistaken for a different cookie?

Or is this just another referer, a mistake that has been accepted as canon. Referer has the benefit of not being a real word at all though, so is less confusing.
