> By low light mode on phones I assume you mean image stacking. This requires a stationary subject. Which is a misconception. The entire point of stacking in smartphones is to handle lots of movement in a robust way, and it's surprisingly good at that. You can actually perform similar stacking manually for a camera, the algorithms are well known and there are applications to do just that, for example [1]. There's less benefit on a normal-sized sensor since it can perform much better with a single shot as you pointed out, but there are still valid uses for it in certain scenes where even proper cameras struggle, see [2].
