If you check out the Multilingual Names wiki page [1], there are places where people choose to standardize the default name=* be a combination of two languages or two encodings; eg  fr + nl in Brussels, or Arabic + French in Moroco. If this is going to be adopted by the folks in Belgium, Morocco etc, there should be the choice of specifying two (or 3) languages, to fit with their current preference.

How about "name:language_order=fr;nl"? No confusion possible there,
whereas "name:language=fr;nl" would not specify the order, unless you
define the list of languages to be an ordered list, which AFAIK would be
a new concept to OSM.

And I suspect there may be more communities that will choose this option, to encourage displaying names both in the local langauge and in the official or national language.

So your idea is only for multilingual areas? Seems a bit of a waste.
Combine this with "name:language=fr" in Wallonia, "name:language=nl" in
Flanders, "name:language=de" in the Ostkantons, and
"name:language=fr;nl" in Brussels? 

Is it intended to be only for street names? If so,
highway:name:language=* might be required to make that clear. Or does
everything that can have a name need to fit in with this?
