Streets are already transforming 2D information on a 1D line, a bit like a hilbert curve.
GPS has a military use because the military go off-road, but citizens really don't (99.999% of the time).
So yeah, it's another one of those case where software engineers are trying to solve a problem where there was no problem in the first place, because they don't like dealing with standard addresses.
If you want to share a GPS coordinate, just use geohash, and use NATO alphabet if you need to share it orally.
