You could say that, I guess... but there's more to it...
Except for the section in red. The balance is never towards the inside, that is the point !
At skis flat you have no inclination of COM and you're right, we need to create it quickly. If you put any pressure on the inside ski, you're slowing down this process of establishing COM inclination, simply because Newton will push the COM up with the same pressure, right from underneath it. Which is fine, if you just ski on a green run, but it will result in much bigger turns on a steep run.
What you want to do is to direct balance towards the new outside ski instead, which is the one that will need to hold you up at the apex, at max pressure. Not pushing into it, because that also slows down or stops edge angles (COM inclination) but just keeping it engaged and gliding, i.e. balance on it especially as pressure starts to appear.

Let me start easy. Gliding and doing easy turns o a green run. You can get away with anything here, but, you can still lift the new inside foot at skis flat and make the entire turn on the outside ski. While doing this, you can make bigger or smaller turns. You can control the rate of COM inclination even with the foot up - ergo, you don't need to pressure it to slow down COM inclination.
The COM simply falls inside because you lifted that foot...
If you instead at skis flat, push into the inside ski 50%, you won't fall inside anymore - you're stuck. If you push into it 10%, you get some benefit, but reduced balance skills on the outside ski. If this is your "go to turn" you will never be able to establish balance 100% on the outside ski, even when you need it.
Let's ramp it up to high-performance turns on a black run and by that I mean slalom turns, not gliding half mile GS turns. The energy and momentums take over - you no longer talk about weight, but momentum, balance and wheather I'm relaxing and giving into pressure or resisting pressure.
Your COM still needs to establish inclination, this is eased first by the flexing to release, which results usually in a lower COM than otherwise, so it's already lower. If here you again push into the inside ski early, you're slowing down edge angle creation again and your turn shape is screwed! If you push into the outside ski too early, same thing happens, but you'd at least be balanced on it and have more control over that one.
You can also think of it this way: once you commit to pushing into the inside ski, you will not reduce that push. Pressure only increases through a turn, it doesn't decrease, it's not like just before the apex you have time to decide to shift balance significantly, so you'll end up at the max pressure phase, with what, 30% weight on the inside leg, which is bent and now holding up 60% of your body mass, at 2g? Why - when the outside is long and you're stacked and balanced over it? If you've not established that balance over the outside leg, then yes - you will have to get your inside leg tired while turning... and likely also never achieve the big angles you're thinking of...
anyways, hope it helps. As you progress and start to ski like this, you start to realize that it's all about establishing balance as early as possible and directed to where you need it to be.
Using the inside foot as a crutch on a regular basis will impair balance and reduce performance and progress.
That is really the crux of my point and why I will keep insisting on the 100%!
cheers.
p.s. in terms of the "turn model worth teaching" - there are several releases and each valid in different tactics and resulting in different turn models and I teach them all, but if you'd look for the "
ideal or
go-to turn model worth teaching", yes.
