I'd more bet on spatial distribution of objects based on their age. Its
not a matter of how many mappers you have but how often they change and
fix stuff e.g. how capable they are in validating and fixing stuff.

If you have "new" objects e.g. max age of 6 months distributed all over
the place you can assume a well maintained area.

So one could filter nodes from the planet or an extract which have an
age less then e.g. 6 month and visualize their density in relation to
the total number of nodes.

I'd wish there were a JOSM Plugin showing some activity/maintainer score
for a viewed area. When i do armchair mapping that would influence my
willingness to take no hostages. If its a well mapped and maintained
area i'd rather put up a note with inconsistencies - If its an area
somebody mapped back in 2009 and didnt touch since then i am less
reluctant to scrap some of the data and remap.
