You can also do it in software by just recording IMU with high precision time stamps (a lot of camera sensors have a gpio they can interrupt on even every scan line) and post-processing. There’s cool techniques where they can remove various issues in rolling shutter through this technique to get global-shutter like quality and removing camera-movement induced motion blur. I haven’t heard of it applied to super res but I don’t see why not. I think Google uses similar techniques to implement their software HDR solution which takes 3 back to back snapshots at different exposure levels and merges them.

Newer Sony mirrorless cameras embed gyroscope data into videos for further stabilization of the image when IBIS is not enough
Theoretically, with 30FPS cameras like Sony A1 and said gyroscope data, you can create super resolution images.
IIRC Olympus' some handheld super resolution modes use both shake and sensor shift to increase resolution.
