Yes I understand the foundations of both of your points. Now, if we do decide to take those RmR tournaments into account, with the same weightage as others, that's basically changing the rules of the game, after it has begun. Here's why:
It was clarified at the start of the current RmR points system in early 2020, that these region-specific RmR tournaments will only be used to determine regional seeding at majors, and will not have any further implications, per se. (Regular Team ranking update is a different thing, mind you).
With that reason, in IEM NY CIS for example, on the 1st day of the tournament before it had even begun, Blad3 gave a statement that since RmR tournaments don't matter beyond major seeding, and Navi already has secured "Legends" status at the majors (by winning clutch island), they wouldn't play this tournament seriously, and treat it like an extended light-break period. For the reason that it doesn't matter, the team didn't practice, as reported by the coach. As for s1mple, he was said to be late-night partying at bars during that time, proofs being on his Insta and Youtube streams of other streamers. I'm not even talking about Boomich having fever, Perfecto having covid, or Navi forfeiting semi-finals due to it.
Is it fair to say now that all those tournaments are suddenly relevant? My answer - I am undecided. HLTV hasn't released an official statement anytime recently, about whether it would be counted for HLTV Top20
