The last paragraph of
http://dev.w3.org/csswg/css3-flexbox/#resolving-flexible-lengths already
requires this, no?

As for flex(1), I believe that for simplicity sake, we should say that sets
the preferred size to 0 in non-flex contexts. There's no use-case for doing
this. If authors doing it, they're surely making a mistake and will need to
fix it. So, we should do the behavior simplest to implement/understand.
