I think it's finally over. At least, what was started that led up to the Feb 2021 deadline is over. It was not included on the Regulatory Agenda HHS published in March, which it describes as activities it intends to address "in the foreseeable future."
I was inclined to take the Feb 2021 date as a last kick of the can past Inauguration Day. What I would normally expect of FDA at this juncture is to regroup under the new Administration, figure out what it actually wants to do with this, and then go from there.
