There are a handful of subreddits (for example, one for recovering alcoholics, one for legal advice) that have decided that their value to the community is higher than the value of staying closed. So I think if it does get extended then the eventual outcome is that "general" subreddits will remain closed, and those dealing with, for lack of a better phrase, vulnerable communities, will show solidarity with weekly blackout days instead.
