If only a handful of people are likely to use the data (inevitable with lots of overlapping catchments), then create it offline (draw it as a separate layer in JOSM and save it). If more than 1 person will use it, post it somewhere. You could add a link on the wiki city page.
But I wouldn't add obscure large-scale geometry to the DB. Obscure tags are tolerable, pretty easy to ignore, and we can hope they get documented. Obscure geometry is just clutter. Richard
