It's not a huge deal but it looks like eBay added a mandatory field for certification if you're listing coins. You have to fill it in for every listing - it doesn't just copy what your last listing had. So if you're like me and all your coins are uncertified, it's one extra click - usually more because you forget about it, get an error message and then have to go back and fill it in. When you are listing dozens of coins it is just another little annoyance.
You might add that this is only applicable on eBay.com (USA) On other eBay platforms you can list any coin you wish and put a grade in the title slabbed or not.
