Each DAO needs to allocate some of its incoming fees to incentivize development.

Well, the above is not exactly correct. The incentive for development is to earn reputation.

However what is true is that a DAO may need to leverage some reputation toward governance-related actions.
For example gradually changing the weight of some posts bit by bit.
This can be accomplished by a work smart contract that allocates a fixed percentage of minted reputation in the desired way.
If no reputation is needed for such initiatives at a given time, it can be burned instead, to preserve fairness.
