No, I don't.  I've only noticed it in a recent datasheet, it appears
to be a very recent change.  (E. g. the ATmega1281 we are using still
start out with SP set to 0.)

I think the initialization would better remain in the startup code, as
it also allows people to customize their stack location easily.
