It probably depends on the granularity in which you are thinking. Some
people approach OSM with the mindset of making a technical drawing and
would love to enter all the details of the dam (ideally in three
dimensions). My aspirations are much simpler and I think that sometimes
it's not only ok but necessary to stylize in order to keep things simple
and maintainable.

So is it the dam's purpose to carry the path? Of course not. ;-) But dam
and path are physically and logically closely related. Like on a bridge
the path runs on top of the dam, pretty much on the line where the dam
and the water meet and without the dam there would be no path. Therefore
I would even go a step further and make the way of the dam and path part
of the multipolygon of the lake, to which it is also strongly related.
