The difference here is that geotagging adds tangible and visible 
benefits and added functionality to sighted users who upload their 
photos (which, I'd assume, still constitute the largest user group on 
Flickr). It'd be a tougher sell to say to people that they must also 
provide alt text routinely (and even retrospectively).

CMSs and authoring tools, in view, are a completely separate beast. In 
my last email I noted how many users (myself included) don't user Flickr 
so much as a publishing platform, but as an online extension of their 
private photo collection, with the ability to share with known 
individuals, friends, family. The use context is different. In the case 
of CMSs used for publication to the wide web, I agree - and many more 
sophisticated systems already do warn about empty alts - but users 
should still be able to consciously leave alt empty, as otherwise 
they'll simply enter some generic text ("photo", "image", "abc", "blah", 
...) if they're forced to enter metadata/alternatives.
