[Tagging] 10 pin Bowling Alley

[Warin]

Hi,


New to me tag leisure=bowling_alley 
https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dbowling_alley


I would have used leisure=sports_centre, sport=10pin for a building 
(armchair mapping from imagery).

leisure=pitch where the area detail is known.


I don't see leisure=stadium being appropriate as I view them as having a 
vertically staggered seating for an audience.


Why does a bowling alley need its own tag?


Thoughts, please.
