It is, however, a lame duck to photographers (and I think many other artists) when compared with Photoshop. Those who want a visual interface to drag sliders around, instanly see how things would look and edit based on tight coupling with that visual perception still choose Photoshop. I have seen many, many artists try Gimp only to go back. Maybe Gimp does not need to be that tool for artists, but if it does its developer community needs to be more engaged with photography crowd.
As a data point: current Adobe licensing model is almost universally hated. If there were a viable option many users would migrate. I would (and I am just a hobbyist). And it is not for lack of trying -- they do try Gimp (and Liminar, and Affinity and such). But the fact that they curse Adobe but still use Photoshop tells you a lot about the fact that Gimp just does not cut it for them. My 2c.
