I was not sure if the Gov forum was family friendly so edited out my loose wording, thanks for providing the extra context though. I am highly skeptical of Op grants being easily granted to well capitalised projects where there is a large potential for it to be siphoned off chain and back to mainnet.
See my expose on Perpetual Protocol that did something more explicit here:
I can see a similar eventuality in this instance although not as blatant or as deliberate, but due to Curve’s main mechanisms being outside of Optimism.
