That is close to the grassroot style of OSM - people use the tags they
think apply the best in their experience (and as common as possible at
the same time) instead of strictly defined types.

Definition should help to understand what it is and how to use it, not
to start from some supposed higher state of GIS knowledge, because the
world is too wide and different.

We have very vague definitions for highway types and people are able to
use UK types in a flexible way without one single definition (nor
applying real UK road system in every country, of course). It is not
elegant nor strict, but it works as a universal road skeleton. Subtags
can be used when needed.

Being an open space does not have to define the usage, just like being a
building does not have to define the use of the object. You can say "a
parking X located at the Y square" and this sounds quite reasonable - it
does not have to be "a parking called Y square".

I think the square is close to the street. There are multiple "List of
streets and squares in..." on Wikipedia and my own hometown has a
special project about them, including this paragraph in the summary:

/Experts say that "there is no regularity that connects Warsaw squares -
such a common feature is neither shape, location, development, or
equipment. Connected into constellations, they are part of the city with
their character - unique, though not perfect. The conclusion of the
analysis of 30 out of over 60 Warsaw squares is confirmation of
intuition that their main feature is randomness. We treated this lack of
regularity as a rule - giving a lot of freedom, allowing incident
design, sanctioning the paradox as a building block. "/


If one city does not have a clear definition, I don't expect we will
have one for the whole world.

There are some of the different functions the squares can have from my

- meeting space

- recreation space

- decorative space

- part of the address/location system

- commemorative place

- transportation hub
