Well that was easier than I thought. I was poking around my long-dormant CouchSurfing profile last week when I realised Wu isn’t an option for languages on one’s profile, though Cantonese is and of course Mandarin as well. So I sent them an email. They asked for the ISO code (”wuu” in this case), a link to the Wikipedia article on the missing language and maybe an explanation beyond that. So I sent it all in, and sure enough a few days later, Wu is now available.

Go, CouchSurfers! Declare your Wu status and find like-mindedtongued surfers.

This also opens up a new category here at the Annals: Wu Evangelism. Mad props to CouchSurfing.com for being open to this sort of thing.
