I can't find examples right now, but I have encountered various problems
along these lines in the past, including:
* The feed suddenly becomes empty.
* A new blog has a 'feed' link, but it never works.
* A blog's feed URL changes, but doesn't redirect.
* A feed is misformatted in a way which causes it to be ignored.
* The content of a feed is misformatted, such that in a feed reader its
display is mangled, such as HTML tags and entities showing, or spaces
having been squeezed out from around tags such that linked words don't
have spaces around them.
* The content of a feed has certain critical information, such as an
image, stripped from it, such that it makes no sense, or has a
different meaning from the full post.
* The content of a feed has certain critical mark-up stripped from it,
such as <sup> around exponents in a mathematical expression rendering
"36" where "3 to the power of 6" was intended.
In all cases the HTML version of the blog had correctly displaying and
updating content; only the feed was affected by the issues. This
usually left the author unaware of the problem, as they don't subscribe
to their own blog.

I believe that to be true for at least most of the above cases I
encountered. However that obviously wasn't sufficient to avoid the

Not many. But that's quite possibly because of the effort involved in
doing so. The algorithm in the HTML 5 spec would allow some categories
of handcrafted pages to gain feeds for free.
I've often encountered webpages which I wished had feeds but don't.
It's possible that an algorithm such as this would encourage more pages
to do so.
