"Whether it should be standardized is a matter of debate." In the same way that vaccines are `debatable'. To export an accurate, up to date model of roads (and road data) and optionally building layouts should absolutely be the norm. Nor does a standardized export format necessitate using a single uniform GIS solution, of which I've had to inter-operate with a number. The real world digitizes spectacularly well, a lot of people just make poor choices and make excuses (or worse, buy nonsensical excuses) for not helping in getting there.

The real world digitizes spectacularly well No, it doesn't. If it did, then the surveying industry would be out of business. Yet every time a building is permitted in the United States, surveys are done. Here's an example for a recent project surveyed in Chicago just this year: West Roosevelt Road; South Clark Street; a line beginning at a point 116 feet north of vacated West 16″‘ Street as measured along the west line of South Clark Street that is westerly 135.20 feet along the arc of a circle having a radius of 375.00 feet concave northerly and whose chord bears north 79 degrees 49 minutes 52 seconds west a distance of 135.20 feet; a line north 69 degrees 46 minutes 04 seconds west a distance of 101.85 feet; a line north 69 degrees 49 minutes 57 seconds west a distance of 26.00 feet; a line along the arc of a circle having a radius of 407.80 feet concave southerly and whose chord bears north 75 degrees 52 minutes 04 seconds west a distance of 85.51 feet a distance of westerly 85.67 feet; a line north 83 degrees 47 minutes 05 seconds west a distance of 164.45 feet; a line north 69 degrees 43 minutes 24 seconds west a distance of 25.16 feet; a line north 43 degrees 07 minutes 24 seconds west a distance of 31.91 feet to a point on the easterly dock line of the former South Branch of the Chicago River; a line south 46 degrees 47 minutes 47 seconds west along the easterly dock line of the former South Branch of the Chicago River a distance of 73.33 feet; a line south 89 degrees 54 minutes 55 seconds west a distance of 32.69 feet; a line south 49 degrees 36 minutes 35 seconds a distance of 46.38 feet; a line north 89 degrees 54 minutes 55 seconds east a distance of 296.25 feet; a line easterly along the arc of a circle having a radius of 375.00 feet concave southerly and whose chord bears south 78 degrees 32 minutes 39 seconds east a distance of 109.97 feet for a distance of 110.36 feet; a line south 69 degrees 46 minutes 04 seconds east a distance o f 136.90 feet; a line easterly along the arc of a circle having a radius of 391.00 feet concave northerly and whose chord bears south 79 degrees 33 minutes 50 seconds east a distance of 135.64 feet for a distance of 136.33 feet; South Clark Street; vacated West 16″‘ Street; a line 155.40 feet west of and parallel to South Clark Street; the north line of vacated West 16″” Street; and the South Branch of the Chicago River Digitize that.

  You have this somewhat backwards. Cities have loads of data that define property lines. They could keep it on paper, but more and more they keep it in computers now. Surveyors take that digital data and convert it into its precise real world marks. This has literally nothing to do with whether the real world digitizes well, and if really stretched only proves that it certainly does because that's the entire basis of property grants. Further, pointing out a massive civic project in the middle of a large city as some sort of counterpoint, when it is in reality still not that complex at all, doesn't make your case.
