Well, I'll give James the opposite answer then:
Language Variants are not *just* a social and cultural issue, either. There are real technical issues to address, having to do with how we manage "slightly forked" wikis, how we maintain code which is not used by enwiki, and the technical limitations of the three basic approaches which have been attempted to date (Content Translation tools, Language Converter, forked wikis with manual synchronization).
So, let's talk about the technical issues at the Developer summit. I'll show you the code to support LanguageConverter in Parsoid, let's talk about what it would take to make this work in Visual Editor and/or for HTML page views (targeting mobile performance).
And then we can discuss the highly technical RFC regarding "Glossary" support in core mediawiki: https://www.mediawiki.org/wiki/Requests_for_comment/Scoped_language_converte...
I think there is plenty of technical content to discuss. And non-technical issues to keep in mind, and should inform the technical discussion.
But if you don't think it's worth discussing, then don't come. ;) There are three other different talks at the same time... --scott
