I never found an updated document listing all the updated revisions. This is the most updated one that I know: https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#new-style-revision-codes-in-use

Anyway, if you tested it, it is fine :)

The docs don't mention it, sadly, but they also state, that they "are not an exhaustive list", so i guess it's just undocumented.
I have a new CM4 here though, and it states revision a03141 (a is for 1 GB RAM) ;)

Yes, I sadly noticed the "are not an exhaustive list" statement.
