The obvious question is, why are you doing this for 2020 and not for 2021, after just extending the benefits for another six months or so?  The answer is, that would add to the price tag and we are working with this darn $1.9 trillion limit.  We'll come back later and exclude 2021.  Like, maybe by next March.
