kdump does not need swap with the same size as RAM.
It doesn't need swap at all.

Unfortunately, I wouldn't know where to look to find the source feature request for that in our products.
Welcome to the club. ;-( When we rewrote the YaST storage stack, it was pretty much impossible to figure out the old requirements, so we reverse engineered them by identifying existing features and a lot of common sense^W^W Kentucky windage. And that was one area where that was reasonably easy to do.
Ok, that's an easy enough explanation. I'll open a JIRA ticket to
remove that requirement.
