I agree that much of it is mental but some of the best players I know including three plus index players that are in their late 50's or early 60's, now putt with a long putter or arm lock putter after decades of putting conventional. Sometimes a new grip or type of putter can be part of the solution.
There is some merit in making these changes to address a mental issue.
Taking the hands out of the stroke effectively takes the part of the brain that worries out of the stroke. It isn't like people have yippy shoulders. That stuff is almost always in the hands. This won't fix the underlying problem but will mitigate it quite a bit and help with confidence which is a nice little cyclical effect.
