Discussion about proposal for multilingual Wiktionary

I am cleaning Requests for new languages [1] at Meta. Some of the
requests are clearly out of the Language committee scope, and they
need wider discussion for concluding them.

One of such requests is for multilingual Wiktionary [2]. Please,
discuss here (at foundation-l; I am sending this message to
wiktionary-l to poke those who are not at foundation-l) or on wiki at
the page [2].
