Actually it will be the opposite. Everybody in the industry knows DHCP and
understands the pull/refresh model. In the absence of a counterweight, that
model will end up being used everywhere. In my experience, folks suggest
disabling SLAAC at the first sign of problems caused by the operator
assuming the pull model... unless disabling SLAAC it breaks some real
functionality. I've seen this happen quite often, for many reasons (driver
bugs, firmware bugs, wireless controller bugs, etc).
