That's definitely my issue: over the years, we have accumulated more and more and more of these names. When someone talks about iOS 4 or iOS 7 in some article I am reading, I know what they are talking about and the extent to which the version matters; but, when someone talks about macOS Gaviota, I have to think "wait, was that the one that just came out, or was that one of the ones I haven't had to think about in a decade? oh shit... maybe it's the one that got announced today and I just haven't heard the name yet?!".

(That said, I will also note that frustration is not inherently constant even when something is truly static: sometimes you get used to something over time and it stops bothering you, while other times it slowly drives you mad.)
