you seem to imply that there is just one way to look at the world. A=B with
subtypes of B, but a wall engraving is something completely different
(artwork) than a hedge or a ruin of an ancient religious site, all of which
can come in the form of a maze.
E.g. we are _not_ tagging man_made=metal_plate and then distinguish
Instead we use building=roof for all kinds of roofs and historic=memorial
for some kinds of memorials, and don't care whether they are made of a
metal plate or not.
There are infinite ways to structure / classify / interpret the world,
which are "main classes" and which are "sub classes" is something that
evolves within our open tagging system. There is no "usual OSM practise" in
a way it would determine how to classify mazes.

to describe what kind of object?
