Not necessarily, this is why i asked for the practical meaning of "the
extend of a settlement".
As i read it "not explicitly defined" just means it is not directly
observable on the ground but that does not necessarily mean it is not
practically verifiable. To give an abstract example - you could for
example implicitly define a city area as the sum of all points on the
surface that are closer to this city centre than to any other city
centre. This would not make much sense and it would make even less
sense to map this as an area but this is theoretically a well defined
concept of a city area that is not explicitly defined.
Regarding names of geographic features - these are rarely verifiable on
the ground, especially for natural objects, verifiability here often is
equivalent to "you get consistent answers if you ask locals about the
name of this feature".
