Not really, it's just more like things are stretched a bit at the bottom to make a bottom realistic.
In RM, if you arrive in the town in the forest being menaced by some creature, the town folk are not 0 level 1-8 HP place holding drones who exist to offer services and act the part of straw victims.
That's because the lanky teenager cutting hay is first level, all the late teens are first level. . .their parents are higher than first level. . .
When I was 17, I wouldn't say I was self sufficient and ready to handle anything thrown my way (though I might have thought so at the time).
The issue, is that 1st level in RM does not mean what it means in some systems, which is:
"Starting out, but at least a full factor superior to the ordinary drones that make up the non adventuring masses."
in RM it's:
"I am just getting started on my life path, a teenager full of youthful vigor, but short on experience. . ."
To use a real life comparrison:
Rarely would a squad of 18 year old privates be sent out independently, they'd usually be lead by a 20something or 30something NCO. . .and that's not accidental. . .
When seriously wounded in the field, the 18 year old trained as a medic does what he can to stabilize the injury, so the wounded can then be carried to help.
The better paid, older, less expendable medical people await at the field hospital to take care of them.
So there's magic in play. . .when you're 1st level you do magic first aid, when you're 5th you do magical field medic, when 10th magical minor doctoring and when 20th magical major doctoring. . .the magic part just skips most of the recovery time.
But the 17 year old lifeguard with a first aid course under his belt doesn't sew your severed hand back on at the side of the pool, he just keeps you from dying, and they get you to a hospital where a team of surgeons with a combined medical experience of over 100 years sews your hand back on.
It's a realism factor, that is intended to make combat scary, and also to force low level PCs to either pay or obey to get access to high end medical care when they need it, and also to make it possible to have realistic populations of low level people, rather than subsuming all non adventurers into a 0 level mass of fairly useless drones.
That doesn't make RM "Better". . ."better" or "worse" in this instance will vary from person to person according to the kind of game they want.
What I think was being said wasn't that RM is objectively superior due to the realism, just that the issue of "Healing is non casual in RM" is an intentional feature of the system, not a mistake or an error. If you're going to ask on an RM board, likely most people will prefer it that way. . .(and some will say it makes the system "better". . .but if they didn't prefer it, why would they be here?)
That said RM is made for tweaking, so tweak it to make it the best game for you, I can assure you I do, and likely everyone else here does to. . .if one person here plays the game vanilla, pure RAW with no tweaks or modifications, I'd be fairly surprised.
