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.
