Why doesn't TW configure resume from swap by default?

Devs, I put my computer to sleep yesterday only to find it would not wake from sleep forcing a hard reset. Checking the config, there was no resume=/dev/by/uuid/..... configured. Leap 15.4 configured this automatically. Is there a reason why TW doesn't configure resume? It was quite a shock to have this laptop, that has always woken from sleep without issue suddenly die trying to wake. Where/how did resume not get set? -- David C. Rankin, J.D.,P.E.
