2 Kilgor, Off the top of my head (what just came to mind in a minute), you'd also need to remove anti-morale in Dragon Utopia when attacking with bone/ghost dragons and AI attacks, remove triggering resist from horn aura, dwarves etc., remove luck, and triggering abilities of units (for example, DK DD, course). Who is going to deal with this and for what purpose? So that one could enable this option unilaterally without the opponent's permission?
As for time savings from quick-battle, I would check it myself, but I am a weak player, so I don't conduct many chain battles; however, if any strong player does a stream (preferably VOD so it remains), I will count the saved time without any problem (by taking saves and conducting the same battles manually; I don't think that in a game up to the 2nd month more than 15 min is saved on one side).

I think when the last HD becomes stable, almost everyone in the CIS community will play with replayable quick-battles; I'm not sure about foreigners, but I think they will get used to it too.

This is maximalism, but oh well. Now, if all this is done (it's a pain in the ass, but done), who can say that fast quick-battle gives an advantage?

Regarding the fact that you essentially play the battle 2 times (1st quick, second manually). I already wrote above:

Replayability is not an advantage in itself, because when attacking neutrals and seeing they are at maximum, you cannot refuse the battle entirely. But the fact that it saves time is a fact.

P.S. Yes, even experienced players find obvious things veeeery hard to grasp
