I agree with pretty much all of that. I never realized how annoying it is to verify, which I have no clue how I didn't, considering in the run that I linked I ended up having to recollect a trophy because of reloading before the game saved.

Everything except for one Riddler trophy in this run actually is possible without using load warps, I just did it because it saves so much time.

Even with that being the case, I don't see this being a very fun thing to devote time to learning to speedrun. I did four runs total and overall it really is more of a chore than anything. Especially that Riddler trophy right beneath the museum.

Overall, looking at the run, I don't think this is something even a small minority of people would want to run. Most of the enjoyment I got out of this was the satisfaction of figuring it all out and then routing it, not from the actual run itself. You're right when you say it's better as a challenge run than a speedrun.

Basic idea is to complete as much of the game as possible as Bruce. This includes collecting all possible Riddler trophies, breaking all possible balloons, and answering the first Zsasz phone call. Physical challenges aren't included because if you do them and then put on the Batsuit and look at the menu, it doesn't say you've done any physical challenges. Whereas the menu does say you've collected trophies and popped balloons even if it's done as Bruce. Biggest problem I can see with this is that it's always possible that more is doable beyond just what is done in my example run. Full example run:
