My friend just performed this on stream and we were wondering if this would make a glitchless run invalid or not, I think it could help a bit with locating the portal room but to me it seems too broken to be considered glitchless

I see everyone in RSG beating the dragon the "normal" way (getting each pillar down, bowing the dragon and then bed him once or twice when he's on the portal and repeat), but in SS most people seem to use another strat where you just place multiple beds in a row as he goes down towards the portal, killing him on the first cycle. I haven't tried this one yet but I was wondering why RSG players weren't using it, is it just too risky / inconsistent that you should only use it in set seed runs?
