You can blame the tools all you want but the basic problem is that  
purporting to encode semantics is a paradigm mismatch with editing  
presentation. And many tool vendors (correctly, IMO) seem to believe  
that the preference of a sizable part of potential customers is to  
edit presentation--not to edit semantics.

text/plain; format=flowed has exactly one semantic construct:  
blockquote. That construct is fundamental to email and automatable by  
mail user agents most of the time. The rest of text/plain;  
format=flowed is presentational, so naturally the format is a better  
match for UIs designed for presentational editing.

(Aside: Email messages as a whole also have supplementary user-entered  
data that is supposed to be mandatory: Subject. And as we all know,  
software cannot force people to write a subject. However, other people  
can make subject writing more compelling if you know that by not  
writing a subject you are more likely to get your message ignored as
