While I may not have been explicit as I should have been, the 
alternative you are asking about was meant only to refer to *author* 
conformance requirements.  User agents (in particular browsers) would be 
expected to process <font color="blue"> as specified by the spec. 
Consistently.  And interoperably.  To the point that authors can depend 
on it, whether or not is is considered fashionable this week.

I know for a fact that there are feed readers that strip out style 
attributes because allowing this information through unfiltered was 
proven unsafe by Mark Pilgrim many years ago.  Allowing in a safe subset 
of style attributes is something many of the better feed readers do 
(including Venus).  But the fact remains that <font> reaches more 
readers than @style does.

I also feel that I would be remiss if I did not point out that there are 
other alternatives, which I enumerated in my original email.  I also 
still haven't heard definitively that the text that exists in the 
current draft (in particular, in the section on "Authoring tools and 
markup generators") breaks Mozilla.
