Comment:
Replying to [comment:6 cheuberg]:
> two reviewer commits added;
Cross-reviewed.
> but I do not understand the explanation why we fall into `QQ^n * n^SR`.
For future investigations I would prefer to have a good explanation once
we intend to fix this pushout explosion.
Rewritten.
> But that would be another ticket.
Ok.
I've merged #19961 and made a link from there to this new explaination.
