I am not sure I understand your arguments. Using wikipedia:language as
key is used in OSM today in many cases. It is consistent with name:language
and other uses of :language in keys, so it makes immediate sense to
OSMers.

Also Wikipedia uses "something:" as their way of doing namespacing. But
generally not for languages, but for User pages, Special pages, Meta
pages etc. Its in the OSM wiki that we use language names in this way,
not in Wikipedia.

This is true, but those interwiki links don't always exist and if they
do, they might not refer to the right page. I'd rather have the option
of adding explicit links to the pages I want to link to. Of course the
interwiki links would work as fallback.

So I think the language must be in the OSM key, not the value.
Translating this into a link is straightforward then:

    wikipedia:en=London => http://en.wikipedia.org/wiki/London

With your way

    wikipedia=en:London 

could be misunderstood as meaning http://en.wikipedia.org/wiki/en:London
which could exist.
