Sounds good. Other people have also requested this, so I've changed the
repeat model a little bit and now it copes with this case.

The spec now only supports interleaved. You can do stacked by using
different containers (e.g. put each stack in a separate <div>).

I used "repeat-template".

I'm not sure I understand the use case for this.

Not sure what you mean by "not ancestor repetition blocks" here.
