Ultimately I am not a huge fan of the "what if" type scenarios, aka alternate versions of various characters. To me "my loki" had his character arc, and ultimately the god of mischief died for the love of his brother. A cool ending, so I don't want Loki to come back. I would like some character deaths to actually have meaning and not just be fake-outs all the time.
That said, if they are going to do it I think the tv shows are the best venue to do it. You can tell these encapsulated stories that hopefully do not greatly change the MCU like Wandavision and Falcon did. I personally don't want this Loki to go "mainsteam".
Others will of course, its just personal preference.
