It's the simplest answer.  Those display values had their baselines
defined that way for a reason.  There's no real reason to mix, say,
display:block and display:inline-block - they're treated identically
by Flexbox otherwise, so you might as well declare all the children as
one or the other if you want a particular baseline out of all of them.

On the other hand, table cells do their alignment with a special
definition, which you modified in your original post.  Hm.

Ojan, Tony, Alex, Daniel, do you have any particular opinion on this?
I can specify it either way - we can either keep the current "flexbox
items have their normal baselines, based on their display value" or
determine the baseline the same way that table-cells do.

Also, what are all of you doing currently for the baseline of the
flexbox itself (for both 'row' and 'column' flexboxes, if it makes a
difference, and for the special case when the baseline of all the
children is perpendicular to the direction of the flexbox)?
