No, I am not trying to kill anyone off. What I AM suggesting is that we need to clearly identify the REAL needs. I may be wrong, but it seems to me that the following stand out. None of them mandate big leather boots.
* Keep your feet warm
* Provide adequate connection to crampons
* Deal with overnight freezing
Now, we do know that uncomfortable boots often fail the first requirement. I remember one girl in Nepal (>5,000 m) in tears of agony because her double plastic boots were the wrong shape or size and were nearly giving her frostbite. (My light leather boots were comfortable and warm.) In addition, I have worn comfortable joggers in winter on the snow on snowshoes and been safe and happy. Yes, they were 1/2 a size larger to accommodate an extra layer of thick socks. They were warm.
Can joggers handle crampons? Experience shows they can. To be sure, step-ins don't work with crampons very well, but step-ins were designed for big boots. You need a different design of crampon - an older design. The one thing you have to watch with crampons is that the strap over the arch of the foot does not pull down too hard and restrict blood flow. That's a design issue with the crampons.
I will add here that if you want to go extreme ice climbing you will need Darth Vaders for the support, just as you need them for downhill skis these days. That is a different story.
The problem of freezing overnight was handled for 'big boots' by the invention of inner boots which can be worn inside a sleeping bag or quilt, and dried out there. But realise this: inner boots are only one solution to the real problem of warmth. If you are going to wear some sort of boot inside your SB, then there is no reason why you could not wear, or store, your joggers in your SB. Many is the time I have stored my joggers or my ski boots at the foot of my quilt to stop them freezing. Standard practice.
What I have been suggesting will not kill beginners (or anyone else) if done correctly. On the other hand, inexperience WILL kill beginners, regardless of footwear. It's a bit like the old (and hopefully obsolete) argument to the effect that 'you MUST wear full GoreTex in the wet and the snow or you will die'. Another vested interest.
Perhaps this is a good place to emphasise that the snow country can be lethal, and that you should NOT charge in and hope for the best. Venture slowly and learn as you go, keeping warmth and survival always a clear priority.
