Prop 448: Signalling Proposal for OSMO/MARS incentives

This is a signalling proposal to include the OSMO/MARS pool (#907) into the set of assets that receive OSMO liquidity incentives.

After this proposal has passed governance, this pool will be added to the regular incentive program of OSMO when created and will begin the onboarding process.

This proposal is timed to provide OSMO incentives at the end of the 30 day Mars external incentives.
