It is ironic to criticise yEarn for maximizing yield for its depositors, at an equal footing with everyone in the market, all while overlooking the elephant in the room: CRV being a massively pre-mined and poorly designed token, and its contracts are proprietary.
While I am in favor of @redarmanino idea that in principle it may be sound for YFI Treasury to hodl some governance tokens, CRV is certainly not one to hodl.
Another reason not to hodl CRV is that yEarn will probably have its own rent-free stablecoin-optimized AMM one day, once the dust settles and we assess the viability or lack thereof of other options like Swerve and Shell.
