Your concern is valid here. The best way to approach this is to limit powers without handcuffing the committee (which would make it meaningless). I suggest that we have some max allocation, which the community is comfortable with over some period (I recommend weekly or monthly). We then enumerate all the areas we would like rewards to be directed to (e.g. aave, stkaave, idle, comp, uni pool, etc.) and the committee is responsible for allocating the max allocation among those pools.
For example:
Note: numbers are just hypothetical
Community Driven Parameters
Max Allocation: 100k PAL / month
Committee Driven Parameters
Aave: 20%
stkAave: 10%
Comp: 10%
Uni: 10%
Idle: 10%
Unallocated: 50%
This will make the committee’s job more straight forward and mitigate the risk to the community while avoiding handcuffing them. If the committee wants to change the max rewards, the can ask the community and provide justification. There should also be a financial incentive to be a committee member, although I expect it would not be a full time job - so either we consider adding responsibilities or we make it a modest monthly pay.
