This does make sense and I'll be honest this is pretty much how my mom prepped it for me when I was a kid. When she grew up (she's Carribean) she would just straight up grab one from the tree outside her house, slice open the top a bit and squeeze the mango almost into chunks inside the peel and would use it like it's own container.

Nowadays I do try to slice it up and remove the peel, but I'll be completely honest I always make a damn mess of it
