The USG has to go through a very length period of coming up with a proposed rule. Allowing comments to be made about it, adjusting (or not) the rule based on those comments, and then finally submitting the final rule.
Nobody at USCIS wrote this document yesterday and published this today. This is the result of years of work. Do you seriously expect the USG to shut down anything they don't think they can finish under the current administration?
