Personally, I’m a fan of just requiring whitespace around operators. I find expressions hard to read otherwise, so think it’s bad practice, but I also find precedence rules awkward in all but the simplest expressions, so like to use parentheses a lot, which mean I don’t necessarily need whitespace-based grouping to make expressions clearer, eg: “a/b + c” I would just write as “(a / b) + c” anyway. I’ve been programming for 20 years so it’s not just unfamiliarity, I guess I just found these things cause me speed bumps needlessly.
