Description

Incomplete, split out from T68889: Improve UV packing to pack more tightly (not just considering bounding boxes)

Sounds like Smart UV project in 3d view -> seams from islands in UV editor.

Or is it something different?

Smart UV project isn't exactly the most usable UV unwrapping solution on the market. Compared to recent advancements in UV unwrapping available in other tools (ex: Substance Painter/Houdini/InstaLOD), it really not any good.
The current "Smart" UV is just a dirty hack based on edge angles with no real consideration for the flow of a model's topology or best practices for unwrapping. The proposed tool should be much more robust than that.

Well, Smart UV is not a dirty hack, it is just simplest representation of a linear algorithm, that allow to work fast with heavy meshes, or when topology doesnot mean, having a predictable result)
It does it job nice, completing its goal, but the problem that such goal is not universal.

Anyway, it is nice to know that surface/topology tension dependent autoseaming tool was proposed, it will be very helpful)
