This is a good argument for cutting it. It is true that any use case for box-ordinal-group applies just as well to divs or floats. In all these cases it I a baby step towards what XSLT does (and that is usually the direction we don't encourage for CSS). And all these cases are easily solved by script.

Why is reordering more important for flexbox than for table cells or inline-blocks or maybe even floated blocks? I understand wanting to limit the scope, but I don't see why flexboxes should be the corner of CSS to have this super-feature, instead of in other display/flow models.

Not really. As it is, having reordering in Flexbox complicates implementation.

I predict that somebody will fill a Flexbox with thousands of items and then use box-ordinal-group for sorting, and expect reasonable performance. Then Flexbox layout not only needs a secondary storage for child order and quicksort. Neither is rocket science, but if it needs to be there it really should have a strong reason.

I am not saying there is no reason for it. But I personally don't think there is a strong reason for it.

How is that statement any different when applied only to flexbox?

It would be a good idea to contain reordering within flexbox. Even there it seems optional. Applying it everywhere sounds interesting but it is a major complication for implementation and would need strong use cases.
