More Jungle Exp is bad... laners stealing Jungle more than ever; a better solution
Have Smite grant scaling experience from Monsters instead of Monsters themselves granting more experience to all.
What do you think?
If smite grants scaling experience, and you fall behind? You will never catch up.
If you put it on machete, it still limits it to the jungler. But it could give you a way of coming back when you're behind.
It wouldn't scale with your personal level; it would scale with game duration.
So actually then, it gains a rather fair & useful catch-up mechanism.
The reason it's better on Smite than on Machete is because Smite wouldn't require the kill... so if you wanna feed your ADC Red buff, you can while still gaining exp from the monster. Win-win, not giving up your "jungle lane" experience.
Machete doesn't have this capability.
