NTP is just the most common assignment that you'd expect the network to provide
but SLAAC lacks. There are cetainly other tasks that you'd use DHCP for and that
SLAAC is not fitted to service. As far as I know you can't convey PXE
information using SLAAC only, for example.

I know you can MITM, hijack, tamper and twist your client's traffic in order to
ensure they use your designated DNS and NTP servers. My networks usually have
rules for such effect. That said, those things are a last resort. The proper way
to get a client configured is to use the protocols designed for configuring
clients (weird, I know). Spoofings and internal masquerading and such are there
just for when clients suck and I usually set it so a warning is triggered when
such mechanisms need apply.
