And indeed, the emerge -e world may in fact be optional.

A quite from the current draft of the guide [1]:

"""
- You may want to run
# emerge -e world
now. In theory it should not be necessary to do so, but it can not be
100% guaranteed that this is actually the case. ;-)
"""

I think I'd still like to see people run an emerge -e system
regardless...just as an extra safety step to make sure the system
packages are sane.  But my understanding of what can be affected by a
change in CHOST is definitely changed.
