The Czech Republic changed its official name but many places still use the old name. Same with Eswatini, Côte d'Ivoire, Cabo Verde, etc. I suspect name changes aren't that reliable for dating globes since some of them probably have modern borders and former official names.

A Czech here with a small correction. Countries often have a long and a short version of their name. For example "Federal Republic of Germany" aka "Germany".

We didn't change the name, rather we adopted "Czechia" as an official short variant, since we previously didn't have one. So both are correct.

Otherwise I agree with your point. This is just a bit of a pet peeve of mine.

This document was made by a specific globe manufacturer, so it probably isn't meant to be used to date arbitrary globes, but only theirs.

You're dating the data source used by the globe, not the globe itself. But it guarantees a lower limit of age on any globe.
