How do we get this into mainline GIMP? As a GIMP user since it existed, I can say that the default interface "works" but the ux isn't great. This looks like a marked improvement and would give me something more like Inkscapes UI but for raster images instead of vector...

Possibly as part of our in-progress extension platform. The extension infrastructure is already built (e.g. you could package the theme as .gex file and have GIMP recognize it), and we have a GSoC student working on some aspects of it (at the moment, the submission workflow for an online repo of extensions). Once it's ready, we could reach out to the developers of PhotoGIMP and see if they'd be willing to have it included as part of the initial extensions repo - then you could pull it into GIMP directly.

If they were going to mimic a more Photoshop-like UI by default, they would've done it. GIMPshop was around over two decades ago

I thought they were already heading in that direction with the single window mode merging. But ok sure I guess they'll never change anything because a sister project existed 2 decades ago or whatever.
