I don't have an issue with year based OS numbering, I lost track of what OS # we were on years back (and don't get me started on the names). But really should be current year, not car year.
@paul September major release does present that problem, doesn’t it? They could be numbered like the old Mac OS X security releases: “2025-05 macOS release…”. That would minimize the branding impact, though, which likely makes it a non-starter.
