I wouldn't say maximalism so much, as Oobabooga was designed to emulate Automatic1111, where it's a good enough tool by itself, but then it has a strong extension ecosystem, and it can be utilized through other tools via web service. It's not great at any one thing but it's "good enough" pretty much everywhere.
Oobabooga the closest thing we have to maximalism. It has exposure for by far the largest number of parameters/settings/backends compared to all others.
My main point is that the world yearns for a proper "Photoshop for text" - and no one has even tried to make this (closest is oobabooga). All VC backed competitors are not even close to the mark on what they should be doing here.
Everyone in the VC world misunderstands why oobabooga is successful and tries to embrace not maximalism.
Your example product to benchmark yourself against is blender, if you want to serious compete against oobabooga. You need maximalism
