Would you be open to adding a feature allowing for the option of serializing a GradientBooster struct using MessagePack instead of JSON?
If so, I'd be happy to submit a PR to enable it.
Absolutely, PR welcome!
My only request (and maybe this is what you are alluding to), would be that the MesssagePack support be optional, and the user could toggle as a feature dependency.
