Re: [css-grid] [css-align] Grid is now CR, but what about css-align?

Mats: Your summary of "including baselines" is more generic than what
I was referring to. I was specifically talking about align-content:
baseline, not align-self/align-items: baseline.

You're right that "General alignment for blocks" was too specific and
I should have included multicol/tables but it doesn't change my main

Tab: see below.

OK, so that's fine process-wise, but what about the practical impacts?
What assurances are there that these properties/definitions won't
change and that websites won't be broken?

Sorry, yes, I meant former. I should have elaborated on the reasoning:
align-content applies to boxes in their role as containers. The only
container on which we want to implement the properties, for now, is
grid. If we wanted to implement align-content: baseline on grid
*items* that requires changing layout code in other containers,
significantly increasing the complexity of this implementation. What's
more, it would be the *only* align-content value that does anything on
a grid item.

Well yes, that was the proposal -- it is only specified to do anything
for table cells, flex items and grid items. We're not implementing
css-align for table cells. The flex item discussion is essentially the
same as the grid one.
