It can be argued that if CSSWG had accepted fewer drafts then IE folks
might have spent more time on css-flex-1 so that css-flex-1 could have
gone to LC before the code freeze. Or you tell me why that wasn't possible.

Yes, I now this equivalence. The reason I mention 'align-content' is
that the equivalent, 'flex-line-pack', isn't in [1]. I am sorry but I
don't have IE 10 at hand to test if 'flex-line-pack' is really not
supported or not.

*shrug*. In any case, for Flex, I would mostly want to use the shorthand
'flex-flow' but IE 10 only has 'flex-direction' and 'flex-wrap', and I
am unlikely to want to use a Regions that can only flowed from an
<iframe> when WebKit doesn't support it. Can you argue why the status
quo would be the same if CSSWG hadn't accepted these many proposals at once?

That includes you too, yes. ;) (/me is asking for data)
