IMO, probably not, because i586 boxes tend to be small boxes, with
scarce resources, which tend to be administrated, installed and used
differently from "big boxes".

E.g. my >10 years old i586-notebook at home uses a hand-crafted,
minimized install-set of packages, with any package which is not
necessarily required to run this box having been removed or not even
installed. As smolt is non-essential, this machine has never seen smolt.

Also, this machine hasn't seen a "full upgrade" ever since an initial
Fedora install (years ago), but had been updated/upgraded using
networked command-line yum/apt updates/upgrades.
