Yes, we’re still not entirely decided on how to best support UV editing. The aim with all of the mesh tools is to provide an intuitive and straightforward experience for non-modellers, whilst also providing powerful and more advanced facilities where necessary. There’ll almost certainly be more than one way of editing UVs - possibilities include UV unwrapping, to BSP style tweaking per-poly, to a full on UV editor per mesh.
The eventual plan is that Geo 2.0 will supersede BSP. We would like to provide a similar kind of CSG/boolean facility, though this is in the far distance for the moment.
