Without knowing how the Federal system will work, I think you might be underestimating the aptitude of people doing this.No. Because the federal funding will be so big and outrageous that Tesla with it's finely tuned supercharger building machine will be able to take the money and add these chargers at near zero cost, increasing the amount available to Tesla owners even with the other EV's factored in.
This is how things were broken out In California's GFO-21-604 program where Tesla had recently been approved for charger funding
So you specify a requested amount, you specify how much you'll match, I think it might involve written narratives and presentations, and then everything is graded to determine who receives funding.
Elon was talking last year about adding CCS to Superchargers
