The only scenario I can see where it degrades is that you have a dcache

And in my understanding this is exactly the scenario that kernelcore=
should prevent from ever materialize. Providing math guarantees
without kernelcore= is probably futile.
Well, that forces the user to make a different boot-time tradeoff. It's
unsatisfying.
