It also might require splitting the kerbs when there a variations of just a few centimeters. While tagging actual heights explicitly is fine, it is not a general alternative to tagging lowered kerb / higher than normally expected kerb.

The point is that a 'normally expected curb' may be a considerable obstacle to a wheelchair person. And the purpose of this tagging is to indicate wheelchair access difficulties.

If someone wants to map those variations, let them. Most curb heights are not mapped, indeed most curbs are not mapped.
So having someone spend time mapping minor variations may indicate that they think this is important.
Once the 'regular' curb height is measured then it is a simple matter, for most who are not concerned with minor variations, to estimate curbs of similar height in the same area.
