Somebody remarked earlier in the thread that there are places in the US
where the distances are
used as house numbers.  I think the duck test applies.  It doesn't matter
if a house number is
assigned sequentially, or is based upon distance from some specified point,
or is based upon
some mad king throwing darts at a map: if it looks like a house number, is
treated like a house
number, and appears on the house/gate/whatever as a house number, then it's
a house number.
House numbers don't have to be sequential or monotonic, I can think of a
couple of roads in my
town where the house numbers are counter-intuitive.  So it doesn't matter
if those house numbers
were assigned based on a distance along a road, and that subsequent road
remodelling has
resulted in them all being inaccurate without a milepost equation: if it
quacks like a house
number then it's a house number.

If they're not house numbers marked somewhere on the property, and if there
are sometimes
(as the OP has stated) missing markers, and if road remodelling has
rendered the distances
incorrect, then what good is addr:road_marker in those particular

It appears addr:road_marker is only really applicable where all of the
following apply:

1: The number is not marked on the property (otherwise it's a house number,

2) Road remodelling has not significantly changed the distances between the
and the two nearest road markers (so you know it's somewhere between marker
X and
marker Y).

3) Road markers have not been recalibrated following extensive road
