Sorry I didn't participate in the previous conversation, we had a hurricane pass by and had to prepare.
The discussion was excellent and it looks like you ended up with a great option for the setting. I also like you idea of dropping it from the configuration options as most APRS applications don't let the end user configure it since it is ideally a unique identifier to indicate what software (or hardware) is being used.
Note that not all software has moved to using the new repository for identifiers. Actually, most still use the old one. Hopefully the new maintainers end up producing a file similar to the old one using the new data so people can update their lists for software that may no longer be maintained.
Thank you for considering the feedback
