That's exactly what's wrong with the phrasing on that wiki page. You
cannot define "rules" that something is rendered a certain way and
expect renderers to follow them. The wiki tagging pages document how to
represent a certain aspect of reality in the database, and nothing else.

Valid statements could be "tag x is rendered as z by renderer A" or "tag
x is commonly rendered as z". You can describe how renderers interpret a
tag, but you cannot prescribe it.

A closer comparison would be a wiki page that says "shop=florist is
rendered as a red flower".

That wiki page should then be fixed by either removing that statement
entirely, or changing it to "MegaShopMap 2.0 renders shop=florist as a
red flower".

If the tag's definition is based on some widely known standard, you can
even write something like "the tag shop=florist is equivalent to the
'Red Flower' label as defined by SMSB 2011-31337". But that still
doesn't mean that renderers have to use the standardized symbol.
