In my opinion, the RR rule is universal, generally speaking.
Is it justified to make its application/non-application dependent on a specific map? And what if the game is, for example, on XL-U? Or Diamond on a non-standard size? What if a few more popular maps appear in the future? Should we hold a plebiscite for each one, or even worse, adapt the entire set of rules?
If the rules for Mininost change in the future (e.g., control is removed) and the concept of RR becomes irrelevant on it, should we change the rule again? Soon we'll be memorizing kilometers of nuances for each map. ;)
In my opinion, RR either exists or it doesn't.
The ban on RR is really needed on small maps and maps where there is a guard tower within walking distance of the castle. That is, Small, Balance, possibly Panic, and all M-maps. Because on these maps, RR is quite often unstoppable with proper red play.
On those maps where it is difficult to rush red (almost all the others), and with proper blue play, it is even more difficult, banning RR creates more problems than balance. They have already been described.
Regarding Jeb, the question is debatable, but I have much less experience than the community, so I won't insist.
