I would also say it depends. On my home computer I almost never log out of anything. On my work machine, I leave some things logged in but most log out. On my own laptop, which travels everywhere with me, I log out of everything.
Using incognito / private mode browser windows can circumvent some of this.
Using password managers can circumvent some of this.
For those reasons, what I do isn’t as important, IMO, as what I think - for none of us really, as we are not really the normal Internet user pool to draw opinion from;
My opinion is that the option should be there, as it always has been. It’s good UX, and it’s helpful to those that want to be signing out all the time and don’t use another method.
