There’s limitations in ADK, but you can do a lot with it if you’re creative at doing work-arounds. The biggest problems are the lack of documentation (you literally just have to play with things and figure out what those things are doing), and also 95%+ of modders lack any experience (most people just copy existing assets and edit default values to create something slightly different). Very few people create their own custom meshes, very few people code anything past a few blueprint nodes, and I’m assuming less than 1% code anything complex (most, if not all of these people are now being paid by WC to continue working on their mods).
