I mean...they're not really an emerging artist anymore, selling like over 300k and are one of the only BGs that can chart on Melon 24Hits. There's no point if the prize is a comeback show like for Queendom..when TXT get those all the time. Not to mention they're pretty busy, they're promoting everywhere in Japan rn, Soobin's doing MCing, they're also doing a radio show every week, etc etc. They need a break.
It would be nice but there's not really an incentive for them to go aside from "exposure". If you want performances then just wait for year-end award shows lol
