Of course, now that you mention it, I can remember enough of what I read at the time to corroborate this. I actually feel a bit silly for not remembering, then I remember that I’ve been alive for every USB revision, and it’s hard to keep up with this stuff.
I’m reminded of the WiFi renumbering scheme that dropped with Wi-Fi 6, and yes, that is the way that it’s written. I never write it out hyphenated, or usually with numbers, because that’s not how most equipment with those features is labeled; only modern Wi-Fi 6 devices, and those older spec devices produced since its introduction, use the new numbering scheme, rather than 1-2 letter revision name.
Thanks for the correction, and the reminder.
