Thats an interesting point, really great to draw upon your experience in governance across chains! Delegation is mostly sticky but with the upcoming ARB unlocks in March, I do see a nonzero amount finding its way to active delegates.
I can’t think of another case where the most powerful delegates have applied to be a service provider, so we are all breaking new ground here 
My larger concern is with the vortex of power / flywheel that is being created through this proposal.
Revenue earned as service provider → Hiring Staff → Greater capacity to undertake delegate duties → More ARB delegated
I understand it may not be a direct payment, but Gauntlet can offset payments to their employees with the revenue being earned via this proposal.
Overall i echo camelot’s point of creating an RFP before issuing million dollar contracts, to create a level playing field & ascertain needs assessment before getting into a financial comittments.
