If I need a gradient for a background, I prefer perceptually uniform gradients. When I need to mask images, linear gradients make more sense. But that's probably a matter of taste and not only a "technical" decision. For that reason, I think that forcing one or the other is insufficient for catering users needs. For gradients it makes a lot of sense to add an option so the users can choose. It has been discussed that alpha blending in gamma space should be provided, although it's not "correct", to keep the appearance of legacy files. In that particular case, an option is given for people who choose that appearance, even though it's technically incorrect. Why not offering an option for technically *correct* gradients? Anyway, I think it would be much better to make GIMP work properly in linear space (the way light behaves in real world) and worry about gamma correction only in the end, for display and export. If a specific tool needs a temporary flip to gamma and back for whatever reason, that can be added on top of that (ideally as an option, so no technical use is hindered by a personal aesthetic preference). I'm pretty sure that a true linear workflow with some options to specific gamma corrections can make all the linear/gamma modes go away from the precision menu, simplifying the UI and making everything more consistent.
