I did a thorough study of this (details below) and I concluded that we're 
better off removing it. I've removed <input usemap> from the spec.

Out of 3.5 billion or so HTML pages examined in this survey, only 0.00036% 
(about 12000) had a usemap="" attribute on an <input> element pointing to 
a <map> that contained an <area> with both a coords="" attribute and an 
href="" attribute, the latter of which was not the empty string or a 
single "#". These pages were distributed over about 500 separate domains.

This is a sample of those pages, one per domain, strongly biased towards 
front pages -- if a site had an affected front page, that's the page that 
was selected. Any URLs with numbers, ampersands, question marks, and 
commas have been dropped, to make the list easier to manage. I looked at 
some and didn't find any pages that would be negatively affected by 
removing this feature. (Other people looked at some pages from an earlier 
study along the same lines and actually found several pages that would 
work _better_ if you didn't support <input usemap>, too.)
