+1, and it won't be a clearly defined border where some meters more or less
matter or are clearly definable (in contrast e.g. to the position of the
center of a road, which is quite precisely definable).

yes, for the reasons described above: no clear boundaries / fuzzy borders.
A solution could also be a new datatype in OSM for fuzzy objects, (e.g. a
collection of objects and the consumer would create a hull area around
them, possibly also roles for objects that are to exclude), but at least
currently this kind of stuff does not fit into how osm works.

I wish it was like that ;-) (i.e. it was used only for settlements and
parts of them).
There is a majority of values that are intended for settlements, but there
are also others like place=locality (explicitly uninhabited), place=islet,
island, archipelago (uncertain if inhabited) and there are those that are
basically used to put a label for a big administrative entity on the map
(like county, region, state, municipality, borough, country, etc.).

IMHO the island-stuff would fit better in "natural", and the labels for
admin entities do not need "place" either (e.g. could be nodes with the
role "label" on an object tagged with boundary=administrative admin_level=*
name=*). Still place=locality would remain for more or less unspecific
labels for uninhabited place.

Cheers,
Martin
