The Alemannic language (gsw) is supposed to be preferred for people connecting from Switzerland (country code 'CH') according to CLDR, but apparently it doesn't.
It is probably related to the fact that the Wikipedia site in this language is called als.wikipedia.org, and ULS configures an alias for the als -> gsw codes in a non-standard way (because als is also a valid code for another language).

So, this gets more complicated: als.wikipedia actually accepts four languages: gsw, swg, wae and gct.
swg is listed in CLDR under Germany and wae is listed under Liechtenstein and Switzerland. gct is not listed anywhere in CLDR, and I suggested reporting this to CLDR.
Can we and should we redirect all four codes to als?
Change 301115 had a related patch set uploaded (by Nikerabbit):
Move als->gsw override to ext.uls.init
Those other codes never appear in interwiki links, so I don't see why we should add them.
