My questions is, hold it back from what? Having the 4k option is fine,
it's just eliminating the current default which I think is undesirable.
I tried 4k stack, I couldn't measure any improvement in anything (as in
no visible speedup or saving in memory). For an embedded system, where
space is tight and the code paths well known, sure, but I haven't been
able to find or generate any objective improvement, other than some
posts saying smaller is always better. Nothing slows a system down like
a crash, even if it isn't followed by a restore from backup.

Feel free to point me at some results showing major improvement from 4k
stacks, I'm open to data.
