This was discussed extensively on the list and in the f2f meetings,
and won't be revisited.  We have strong experimental evidence that
authors find the model of flexing always starting from width/height
unintuitive, and so we changed the model so that you can easily flex
from a starting value of 0.

Forcing the flexing to start from the min-size is similarly
unintuitive.  That's a constraint, not a declaration of intent.  The
fact that a particular element shouldn't be made smaller than 100px
doesn't mean you want it to start flexing from 100px, particularly if
the other items in the flexbox are starting from 0.
