Nothing at all it’s buttery smooth, only issue is the left hand cup having the first half of threads missing but the rest that are intact and screw in nicely.
What kind of bottom bracket is? You should chase the threads if a new bottom bracket is going in but with the same old one it won't get any worse.
I'd probably still ride it assuming there's enough thread but for someone else I would do it right.
Is there anything wrong with the BB that’s in there now, other than the thread damage?
