I rather suspect that quite a number of sites are unwittingly relying 
on content sniffing right now;  it's not easy to notice that you're 
using it, if you are a page author.

An interesting but hypothetical question is whether they actually 
need to, or whether they could fix the site.  My suspicion is that 
they could easily fix it.

If servers were fixed to omit content-type headers for content when 
they don't know the type (i.e. align with the spec), and browsers 
were fixed to sniff only when content-type was absent, magically 
overnight all at once, I would expect a rough few months as the 
places were found and fixed, and then we'd settle down again.  But it 
isn't going to happen...
