Arrays have regular shape, no embedded arrays

No, I think that's quite explicit already.  So we've already covered that base.

I said:
>> Section 4.7 has a TODO on arrays of arrays. I propose that we specifically do NOT require support of arrays of arrays. Apps can implement that if they want to, but I think we should NOT require support of it until there's more experience with them.

Eike:
>I think that in spreadsheet context there also is no need to support them, and I don't know what it would be good for if an app did that. I'll remove the TODO. Section 4.7 is fine as is, I think.

Agree. Okay, Eike will remove the TODO, and we have one less TODO to do.
