Need to specify side loading mechanism for binaries in order to connect with ID check services. Need to be another BIP tho.

  17 | +A growing number of jurisdictions require software to implement age

I don't see how adding a single field to already non standardized wallet storage formats is worthy of a BIP.

I’m closing this PR, because this proposal has not been submitted to the mailing list for discussion previously, the document has various formatting issues, and it self-assigned a number.
