Observation
Recently, Curve launched the “3pool” comprised of DAI, USDC and USDT. Currently this pool is earning ~40% trading APY and ~85% APY in CRV tokens, without any boost enabled.
Boosting up to 2.5x for this gauge starts on 20/09/2020 17:58:29 UTC. That would bring CRV farming APY over 200% APY, at current rates and gauge weights.
This pool is gas optimised, and will be used as a base pool for future meta pools on Curve. Because this pool is likely to offer the best prices, it will also likely be one of the Curve pools getting the most volume and hence Curve platform trading fees.

Suggestion:
Open a new Vault: "curve.fi/3 LP"
Allow deposits of 3Crv tokens (token address = 0x6c3f90f043a72fa612cbac8115ee7e52bde6e490).
These can be used to automate CRV farming, similar to the Curve.fi y, busd and sbtc LP Vaults.
Additionally, other Vaults (e.g. yETH, yDAI, yUSDT, yUSDC) could plug into the same strategy.
Enabling boost on this strategy would further increase rewards, especially with the veCRV incentives coming up.
Reasoning:
Future APY for this 3pool strategy will very likely be higher than the current strategy of the yPool (StrategyCurveYCRVVoter), which currently handles most of the yVault funds.
