Have my vote!
I think it would be a good ingame solution with the existing tools / mechanics to the problem, that the (overclocked) miner output outruns the belts which would render it useless to overclock rare nodes.
I think the requirement to build many lower tiered belts to supplement higher tiered ones balances out the issue that higher tiered belts become somewhat obsolete since you don't get the transportation of the equal amount for free. Instead, you have to put in more time to get the lower tiered belt system to work. Plus, there's no 1200 units per min belt yet, but the recently released miner mk 3 on pure overclocked to 250% produces exactly that.
Make splitters snap-able to outlets of production facilities and to themselves! pretty pleeeease ;)
