Yandex removing displayed borders doesn't move us in any way closer to borderless world in reality. No country is seriously considering it. It's not a canary for anything - they stopped displaying borders exactly because countries/people care about those a lot.
But it's categorically different. Removing pictures from CVs so that corps are unable to discriminate based on that image still maintains the concept of "employee". Doesn't removing borders effectively remove the concept of "citizen/national"?
The subject of a CV is the human, but the subject of a map is the place. Removal of borders removes the concept of a citizen, but maps are concerned with the concept of an area. Nothing of value is lost. In more practical terms, I have not encountered maps that explicitly mention the concept of a citizen, other than by drawing nation-state borders, or those that are concerned with immigration (but for those, it's a relevant concept).
These border checks are waived, not abolished. In times of crisis, they can (and were, during the Pandemic for example) reinstated. Countries can impose movement restriction for internal regions as well, but these carry a much higher legal overhead.
Also, Schengen borders are transparent only for full EU residents. If your visa and right of abode is restricted to a particular country, the borders are still very relevant.
Even for EU residents, the borders are still relevant as they demarcate places with quite different civil and penal law codes.
That's a big hypothetical. Mapping companies are not the arbiters of where borders exist. Knowledge of where de facto borders are is pretty useful for directions.
A nice fantasy, but something tells me a borderless reality is not in our near term or distant future. Maybe by the time Star Trek is more fact than fiction
