The question is what we both should ship or not. fantasai's reply to
that thread was:

So, the point of my comment was to reach an agreement between all the
parties (Chromium, Firefox and the CSS WG) about which things are stable
enough to ship and which not.
Of course, Chromium wants to ship the same than Firefox to avoid
interoperability issues.

We've been discussing this topic with the spec editors for a long time
(more than 1 year already).
In our opinion the spec was never clear enough, first it pointed to
Flexbox, later that was changed and it had its own text, now it points
to Flexbox again.

That's why we've been trying to clarify the expected behavior in this
issue (for a while already):

As you can see there, we've different implementations so IMHO the spec
text is not clear. You think Firefox is right but fantasai agrees with
Chromium behavior on stretch vs start. So we have to clarify that.
The change I propose to the spec is to clarify this so we're all in the
same page. I don't want to change the behavior but understand properly
which is the expected one as it doesn't seem clear for me.
My goal is that both browsers behave the same here. And that future
browsers implementing the spec do it too.
