Just need to make sure your module doesn't get too big or unwieldy. I work in a codebase with some "module" C files with a litany of global statics and it's very difficult to understand the possible states it can be in or test it. I agree that so long as overall complexity is limited these things can be OK. As soon as you're reading and writing a global in multiple locations though I would be extremely, extremely wary.
