I like the sound of this too -- one thing though.  It sounds like with 
your proposed semantics, the 50px here would be ignored:

  <div style="display: flexbox">
    <div style="flex: 0 0 50px"/>

That seems undesirable.

(With your proposed semantics, I suppose the correct markup to achieve 
the above would be just "width: 50px" instead of "flex: 0 0 50px".  But 
I bet authors would probably be confused about why "flex: 0 0 50px" 
doesn't work, especially when "flex: 1 0 50px" works...  Not sure how 
much this matters.)
