Perhaps it would be nice to ship a similar tool (or just a textual table as documentation) in the amd64-microcode package. I agree that it is not too easy to verify your AMD CPU microcode is indeed up-to-date with the latest microcode shipped in the package (or available from AMD), especially if you are not too familiar with all the details – like how /proc/cpuinfo reports the family and model numbers in decimal and not in hex, unlike everywhere else. Related bug report discussion with pretty good analysis and ideas from Matt Taggart: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1076703#30
