read the page about forests (or the current discussion on
leisure=common): it doesn't matter *anymore* if some contributors make
a difference between the 2, in the end it's impossible to separate the
different meanings.
The only solution is to create other tags to better describe
this difference.

as for the plate, imho I would use website, but maybe url=*
you said you added an url :)

but if it's a valid argument, let's split the issue in 2 :
for all poi (shop, office, craft, bar, restaurant), does phone
and contact:phone have the same meaning or you have another undocumented
meaning that explain it's not the same ?
and email<>contact:email ?
