People can use tools in various ways. We cannot prevent that. But it 
does not need to dictate the design of tools. People can use hammers as 
toothpicks, but hammer manufacturers don't make hammers softer for this 
reason.

So? Whose problem is this? Generators have generated nonsensical alt 
attributes for years, e.g. inserting the filename and number of bytes. 
Keeping the attribute required won't make much difference.

And it is appropriate to judge that generation of HTML has problems, 
when the markup contains img elements without alt attributes. There is 
no reason why this possibility should be taken away. It is true that 
generator vendors can cheat by emitting alt="". We can't really prevent 
that. You seem to be worried about the possibility that keeping alt 
attribute required somehow pushes or forces vendors into doing such 
things to stay competitive. But this sounds highly speculative.

We know that generators and other software may produce documents without 
a title element or with a dummy or bogus title element like <title>New 
document</title>. And surely there are situations where an automatic 
generator has no way of deciding on an appropriate title element without 
consulting the user. So should there also be an exception allowing the 
omission of the title element, to avoid the assumed reaction by Alice, 
making her generator produce <title></title> or something worse?
