Your assessment is wrong, I'm glad to say.  ;)

The behavior was changed last September (see 
https://bugzilla.mozilla.org/show_bug.cgi?id=394416) and Firefox 3.5 
will be shipping with a much more restrictive feed sniffer.  In 
particular, it treats http://status.aws.amazon.com/rss/EC2API.rss as 
text/plain.

The HTML5 proposal was fairly instrumental in removing text/plain from 
the list of types subject to feed sniffing, for what it's worth (as the 
bug makes clear).
