@dontdosadness Ok, pushback time. Most changes are sound and long coming, but some are a matter of preference and others are a step back. Long story short: keep the good changes, but don't throw the baby out with the bathwater.
The core work. You basically removed it while pretending that you didn't. What you have left is less of a core workout than the McGill Big 3, which I do daily on top of the RR. It's fine to remove the core portion if you think it's not needed (many do), but it's a sacrifice that not everyone will get behind.
RR also contains the honest recommendation to integrate barbells when possible. You can't work the lower back properly with bodyweight only, so "just do deadlifts". Elsewhere in this discussion you write something to the effect that letting the lower back fall behind the rest of the body is fine. Are you absolutely sure about that? I'll keep doing my deadlifts, thank you very much. That recommendation is not there without a reason, and it shouldn't be removed without a reason.
Pairs and triplets are a very useful way to save time (they don't make the workout longer like you mentioned here, on the contrary). You want to remove them for the sake of "simplicity"? They are not that hard to understand. I know I can continue to do them, but I also think newcomers should continue to learn about them. I'm glad I did.
I also doubt that you made the whole thing "shorter and easier to read". No offence, but you're not a very laconic writer, to put it politely.
In general, I'm opposed to another be-all-end-all routine written by a single character, with all the attached idiosyncrasies (I think that stomach vacuums are better than your precious deadbugs, how do you like that?
). The RR in its current form with obvious mistakes (like 1,3,7) fixed, with information on good practices, sound training principles and tips on tweaking it to one's preference is FINE.
There is no one-size-fits-all routine. We all end up following the discussions, asking for advice and tweaking the RR to our liking and goals. The RR serves as a scaffolding for that and an educational piece, a crash course on the basic information on strength training. Replace the RR with a "perfect" routine and you lose all that.
Don't get me wrong, you offer many improvements. But don't throw away the "wisdom of the crowd", because it doesn't fit into your very bestest perfect routine. And don't push your preferences to replace sound alternatives.
