My opinion? It's that a whole lot of generalisation and ignoring context is going on, as they try and break down the reason for Arceus being Low 1-C down into individual parts and saying that said individual parts don't make sense and don't qualify for Low 1-C, while ignoring that it is only through all these components and context adding together that we get the actual reason why a bunch of staff agreed to upgrade Arceus to Low 1-C in the previous thread when other series have failed fo get that agreement for supposedly 'similar' reasoning.
At the end of the day, fictional comsology and feats are a varied thing, and while we try to trim it down to if you have this statement or this feat then you meet the standards for this, we still have to look at the context of the evidence presented and make our judgements based on that if they meet our standards.
But yes, I still think that encompassing and transcending

the rest of space, time, and not space-time to an infinite degree meets the standards for Low 1-C... which is why I disagreed to Bayonetta being Low 1-C for 'supposedly' similar reasons, pretty sure God of Wars transcending is also similarly lacking in additional context Arceus has so that comparison is mute as well.
