Somewhere I saw a version of Inconsolata with the slashed zero. There was a site at one time that collected all the Inconsolata permutations in one place, but I don't have it offhand.
I'm revising Inconsolata, making it into a variable font, and would like to gather data on the variants out there so I can make it satisfy the largest number of users. Feel free to file an issue on https://github.com/googlefonts/Inconsolata simply stating your preference.
