I've commented on the bug, but basically: I've tested the change on a
problematic machine, and it worked for me. At some point I was running
the multiboot version of memtest, but that didn't work anymore since a
couple of releases.

I don't think it's too useful to SRU; people can boot recent
installation media to run memtest from USB stick as a workaround to the
locally installed one being broken. It might be possible to trigger a
memtest from a remove serial console, but I guess the most common use
case is to locally start it when investigating a hardware issue, or when
installing new hardware.
