#2 A time limit draw
One facet of match finishes that AEW has used from time to time is draws. The time left in a match is constantly revealed by the ring announcer so as to increase the tension for a finish. It came into play with both Darby Allin vs. Cody and Jungle Boy against Le Champion.
When AEW wants to protect both sides of a contest, it uses non-finishes or draws. After Omega and Pac had a 30-minute Iron Man match on the go-home Dynamite, a time constraint probably won't be used again so soon.
It could, however, be an easy way to book themselves out of an actual finish if the feuding factions within the Elite are meant to continue fighting each other. There's been the ongoing storyline of Page's disillusion or aloof behavior when the Elite are involved in confrontations. Omega hasn't really squared off opposing the Bucks many times in AEW, so in order to keep both sides looking strong, a time-limit draw could be the finish. That way, if they wanted to prolong the feud or up the stakes in a series of matches, this type of finish could accomplish just that.
