Removing any such option was not the objective of this thread, just lifting
4K stacks from debug and making it the default. People fortunate enough to
use workloads where some piece of crap code by accident works more often
with the current shared 8K stacks then it does with the unshared 4K stacks
can then still nicely not select it (or fix the code if possible).
I may have worded the initial email a bit too heavily towards 8K
removal, but that was mainly to provoke some discussion. Nothing
should get removed without a fair (and long) warning in
feature-removal-schedule.txt and ofcourse not before we know that the
new option is at least as safe as what we intend to remove, so the
patch really was just intended as a fairly harmless nudge towards
getting 4K stacks into a shape where we can eventually start
considering 8K removal.
