Thanks.

Ouch. I know you said you didn't want to have this discussion (sorry!), but please bear in mind people building SPARQL queries using a UI - they will have serious predicate URI bloat, and no easy way to pick the "right" URI.

I think this would run contra to good URI practice - deliberately creating lots of very similar URIs for the same thing is not ideal. URIs are supposed to be opaque anyway.

I think something like q:method rdfs:label "Method"@en, "Methode"@fr, "Methode"@de, "方法"@zh, … is more common, and more user friendly - even if you have to use q:p17234 instead of q:method.
