Much easier to tag the numerical height of the curb as this avoids the
confusion of words, particularly with different languages, cultures and
climates.
this would require a lot of measurements, while a few classes of heights could
generally be determined by looking at it. 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.
