Sounds weird but think, many of the features one one UI are not needed by many people while some need them. But having those lot of whole features puts load on overall software responsiveness and experience. A simple solution is an option to completely delete a feature if one doesn't need it and can re download it from somewhere like from samsung store or any way if one wants that back in future. In this way won't put pressure on software and one can have desired and adequately fruitfull experience of features.
That's a good idea @GT23 as long as one particular feature isn't connected in someway to another which could cause issues if a person stopped one.
Perhaps send your idea via the feedback section on the Samsung Members App !
