Makes a lot of sense. This is an easy one to support.
The only thing I wonder is how the pools should be segmented relative to Compound.
This proposal is to create an Aave pool for aDAI, aUSDC, and aUSDT.
This would be similar to the Compound pool for cDAI and cUSDC (when that pool launched there was no cUSDT).
So, I wonder if it makes sense to have an Aave pool and a Compound pool, or to have a Aave/Compound DAI pool (aDAI, cDAI) and a Aave Compound USDC pool (aUSDC, cUSDC) and maybe the same for Tether.
