I agree that plat names are borderline. These seem more like an administrative area definition rather than a useful feature, or even micromapping.

The wiki page for Parcels has a whole discussion section on whether those should even be included, and the wiki page for "Tag:place=plot" even has a big red warning header "OSM does not aim to be a land registry. You can add plot data if you want but only where the plot boundaries are actually visible on the ground."
