Wouldn't you be leaving yourself open to early ganks though with that start? As a jungler myself I usually ask my mid laner to keep an eye on which side of the lane they ward (if they bought one) and then rotate round to mid around lvl 3 after getting both buffs for a kill or at least to blow a flash.
It's a very offensive start for sure, but to capitalise on it you'd need to play aggressively which would make you a prime target for some jungle-loving <3
My personal preference if i get lumbered with the mid lane role is to start with 1 faerie charm, 1 ward and a few pots just for that sustain and lane safety![]()
I see what you're saying, but you don't have to push the lane when being aggresive

Also, if your team are calling when they see the jungler and where, you should have a good idea where he'll be heading next and what times he has to clear his jungle etc.
