I mean, really, the height argument is kinda dumb (and I'm including myself in that assessment since I'm talking about it). But like Bonsai said above, the lower the height numbers go, the higher the skill, speed, agility, and strength need to be to compensate.
So if Michkov has Bedard-level skill but Strome-level skating, it's a concern of mine. If you have a guy who's 5'10" who doesn't have elite core strength, he's gonna get bodied by a slower, taller guy... just hard to get around that.
The modern game makes a lot of allowances for height both ways. It's all contextual.
