We'll have to have newer laserscanning for the most iconic race track soon :(

Nah, the section is less than 2km long and as he said there wont be any changes made to the track itself. Just fresh tarmac!

I think that every year are some parts of Nordschleife rebuilt and new surface laid. Maybe they should install permanent laser scanners around it :)
I saw similar Mischa's video about year ago.

Except that they state @4m into the video that the (in)famous bump in that section will be removed, so the track will feel different.

The width shouldn't really change and the elevation changes, camber etc should remain much the same but when something like a large bump is taken out, that will alter the way familiar drivers will approach that section (in real life and on a laser scan). Of course, laser scans aren't about recreating the exact surface of the track - aside from being an overwhelming amount of data, the surface will change from minute to minute, let along month to month and year to year - they're about getting the geometry correct and picking up the major details. If computing power advances far enough, sure, we might be able to take that point cloud data and map it in to a sim 1:1 but that's a long way off (I would love to see it in my lifetime, just from the technical aspect of it, but I doubt it will happen).

This could be achieved if there was a scanned model managed by the track owner or someone else, accessible to the creator of the game. The game would not include its own track model, but only the interpretation of such a model.
If the owner made changes to the track, he would also modify the scanned model, and the game would automatically work with the modified model.
The owner of such a model could then maintain different versions according to the date, and in the game you could choose which configuration in time you prefer.
If the model manager then created a scanned tracks database in the unified format which he would regularly keep up-to-date with different versions, he could licensing them to the creators of various games. The game creator would then only be manipulating the model interpretation according to used engine and other specifications of the game.

Technically probably feasible, but licensing, contracts, money, simulators competition, FIA ... I would love to see it in my lifetime

I doubt this idea is possible due to vast variety of game engines and their requirements to assets' topology, mesh density etc.

I don't think there would be any technical problem that could not be solved by available instruments. Every scan produces topological mesh. It is about density, which should be as detailed as possible, and its range should comprise objects, visible from the track in lower LOD. The mesh would be appended with other informations - surface characteristics, photo scan ... If you have such a model as detailed as possible, anytime you can take its derivative in lower details.
Game maker would create just some kind of bridge to interpret mesh data into his game.
There is a number of games, which called themselves simulations, and bring as real as possible feel of real racing to the simracers. And every team build its own track model from some data. To unify models of the same track would be next point of interest of track owners. They are aware of increasing power of simracing and it is not their welfare to listen that their track is more realistic in one simulation than in the other one.

Actually scan produces point clouds not a topological mesh. It is the job of 3d modellers to recreate the track according to the taken scan data.

Track owners are greedy enough to continue asking huge money for the track licenses. While the money flows I see no reason for them to worry about unifying track models for game developers. For them it would be unnecessary waste of money.
