[Tagging] landuse=reservoir vs water=reservoir

[Tomas Straupis]

Hello

  landuse=reservoir is from original OpenStreetMap water tagging scheme.
  water=reservoir is the newer one ("all blue is natural=water") with
no advantages over previous one. Original (landuse=reservoir) is still
more prominent even with Mapbox/iD's aggressive push for the later
one.

  Now OSM wiki for some reason has a note on landuse=reservoir that
"better alternatives exist". Which in my opinion has no base. In my
opinion both reservoir pages must have similar treatment:
  1. no "better" (especially if newer and less popular is interpreted
as "better")
  2. "alternative" should be mention on both or none of the pages.

  What do you think?
