During my test i didn't see any error on this list, i don't have a big amiibo collection but all my animal crossing figures ( all except 3 amiibo of this series ) and cards ( only series 1 ) give me the same ID as on the list.
Same for the dozen from Super Mario Bros series and the few from Smash Bros Series.
Technically the code can do this, only data are missing.

Anyone can edit these files ( understandable without knowledge in development ) and send them to me for an update or made a fork and a pull request.
