Something like Wikipedia's [[ https://en.wikipedia.org/wiki/Template:Authority_control | Template:Authority control ]], except for ISBN/EAN/USB, mostly for set pages. Ideally it should support multiple different values for each identifier, with some mechanism for detailing what each value corresponds to (e.g. [[ https://yugipedia.com/wiki/Gold_Series_2012 | Gold Series 2012 ]] has different EANs for the Japanese and Korean versions). It may be worth investigating whether sets have ever been assigned any other identifiers anywhere (e.g. [[ https://en.wikipedia.org/wiki/International_Standard_Serial_Number | ISSN ]] and [[ https://en.wikipedia.org/wiki/Library_of_Congress_Control_Number | LCCN ]] are worth investigating, I think?).
These identifiers really don't have much business in the infobox, and the vast majority of sets don't currently document any identifiers, so right now they're mostly-pointless overhead in an already heavy and complex infobox template.
Note that this itself probably would't qualify as an [[ https://en.wikipedia.org/wiki/Authority_control | authority control ]] mechanism, so "Authority control" probably wouldn't be an appropriate name for the template (though we should have such a template for e.g. biographical articles).
