[ARFC] Risk Parameters for DAI Update

Temporarily reducing ltv is a relatively low impact measure for a stablecoin as its main goal is to generate yield, but certainly more impactful for sDAI. I second the idea of having a more accurate risk analysis before taking any decision. I also find entertaining that maker turned off the Aave D3M citing high risk (allegedly) but then happily apes 1B into an untested protocol. After all that happened it’s pretty clear to me that Aave DAO should stop providing any incentive to DAI besides minimal integration, therefore i am in favor of removing sDAI from the Merit program, we paid plenty for DAI already
