sdw bp samePlaceAs

I read with interest the minutes from the BP meeting on this topic  https://www.w3.org/2016/11/09-sdwbp-minutes#item05

It seems to me that so:matches is very close to what we need. However, I am swayed by the argument that "samePlaceAs" is a bit more specialised (it seems to say something a bit more. If informally,  about which properties could be substituted).  But I cannot follow the argument from the minutes concerning why  sdw:samePlaceAs should not be defined as  a subproperty of so:matches.
Does it relate to the status of the so ontology?


Further, if we are going to do this at all I suggest a few other basic  informal spatial relationships (of the top of my head) : sdw:NextDoorTo, sdw:closestSimilar, sdw:Nearby (or foaf:basedNear), sdw:sameLocality, sdw:withinEasyReachof, sdw:justDowntheRoadFrom, .... Or something like that.  For commercial businesses, real estate agents, community groups (remember the fete?), social scientists? Most of these would be neither transitive nor  reflexive but  maybe some are symmetric.
