There aren't too many significant code simplifications AFAIKS.

The code simplification comes from the ability to run the same code during
boot that is also running when the full system is operational. I thought
the intend of this whole exercise was to avoid special casing as much as
possible and reduce the amount of code specifically duplicated for boot
situations?

That is one of the advantages, yes. As far as I can see though,
there isn't like *huge* amounts of things you can simplify. And
if it is just a matter of removing a few branches from a few
cold paths, then it isn't necessarily a good reason to push
branches into the slab and page allocators.

I'm not saying we definitely should go one way or the other, I
would just like to wait and see.
