Are there any other examples in any other codex or
faq in which we can draw a parellel?
Edit
I'm not being purposfully obtuse. I always read the can't join units that consist of one model as one model in the unit entry.
Hive tyrants with tyrant guard can have a prime attached.
Further, the rule doesn't say models that are 1+ in a codex. It goes out of its way to say units that only ever consist of a single model. Put it this way, if i point to your riptide unit with 2 drones and ask how many models are in that unit, do you say 1 or 3?
