> does Wayland have a generic way to move+resize windows?
I'm not entirely sure what you mean here or how it is related to hot corners.
The compositor itself can move windows anywhere (it is in full control). A client moving the windows of other clients is not permitted, although compositor-specific interfaces exist for this. There's no standard here because a stacking compositor implements completely different semantics from a tiling compositor. I'm sure that protocol extensions will come up for niche use cases over time.
