These problems do not originate from the number of upgrades/update, they
originate from the _size_ of updates few packages introduce.

Correct.

Well, I would label this an urban legend - Updating recent Fedoras using
yum has not been much of a performance problem, even on slower and older
HW (e.g. a 1GHz i686/512MB)
Admitted, on an 64MB/166MHz i586 w/Fedora 10 yum updates tend to be
"really slow".
However, wrt. to bandwidth, I see another problem: Your strategy of
pushing updates in "big batches", instead of "small chunks".
This makes a significant difference to users with limited bandwidth.
While they could easily poll "small chunks", e.g. once a day (blocking
their network for, e.g. 1 hour), the current strategy would block they
network for very much longer (e.g. 7 hours).
Another aspect related to bandwidth: Revisiting
* the sizes of rpms (e.g. different payload compressors).
* differential updates/rpms.
Seems to me as if these once "hot topics" have dropped off the Fedora
radar, in favor of "strangling/nagging the distro's contributors".
