Thanks Neel, keep this coming - even if only once every few years :) You helped me clarify lots of confusion I had about the existing techniques.

I am a huge fan of steering vectors / control vectors, and I would love to see future research showing if they can be linearly combined together to achieve multiple behaviours simultaneously (I made a post about this). I don't think it's just "internal work" - I think it's a hint to the fact that language semantics can be linearised as vector spaces (I hope I will be able to formalise mathematically this intuition).

Here a proposal of a possible ELK solution using that approach.
