OK.

I don't really trust allnoconfig as a way of determining size changes. 
It can easily be the case that kernel A's allnoconfig happens to pull
in more stuff than kernel B's allnoconfig.

So I do think that one should dive into the details and verify that
particular size changes really are due to unavoidable code bloat,
rather than being due to some unfortunate Kconfig change.

Tht being said, yes, I'm sure that it's getting bigger, overall.
