Guiding discussion questions:
Does astrophysics impact our ability to extract cosmology from small scale lensing regime?
What more numerical work needs to be done to distinguish between the effect of baryonic physics and alternatives to cold dark matter on the small-scale matter power spectrum?
To what degree do we need to worry about higher order lensing effects in the CMB in HD regime?
What typical assumptions about lensing break down on the scales being discussed? (Gaussian, curl-free, weak, etc.)
Can this be done with optical lensing?
