I thought the system was great. I loved that everything was optional, but if you put in the effort, you were rewarded. Having said that the notification system was so awful that it actually made me wish that the system entirely was just removed despite how much I loved the system. Nintendo puts in a great optional system but doesn't give you the option to turn off the notifications of said system- absolutely ridiculous. Let me paint a picture of myself playing the game- I'm fighting enemies with a big smile on my face, then I pick up the treasure they drop and I instantly frown because gameplay halts for 5 seconds to tell me something I already know but don't care about. This happened at least a hundred times in my first playthrough alone. Luckily I played the game in long segments, or I would have been even more annoyed. I did pick up a tip from someone that was extremely helpful- if you pick up a treasure with the beetle it skips the notification. It's stupid that the time taken to take out the beetle and use it actually saves you time in the long run.
