Like what, threaten my employer with an ultimatum? I’m not willing to do that, as the risk/reward balance is way off. I’d find another job if a six day work week is proposed, but not if a four day work week isn’t.

I’d like to see it happen, and soon, so that I have it for most of the remainder of my working years. Back here in reality, I need (and like) this job, and there are much worse limbo states to be in than working for a respectful tech company, from home, hoping for the four day work week.
