If it feels good there’s nothing wrong. However if you are running 130 and moved your saddle forward 1cm, you should probably be running a 120mm stem. You never adjust your saddle for a reach problem. I am assuming your original saddle position was optimized.

I’m running a 130mm stem on my vintage bike. It becomes a balancing act when you are short and have to consider seat tube height into the equation...so your not sitting right on the top tube. If you have more than a fist full of seat post and need a 130mm stem on a standard geometry frame then yes, you could probably benefit being on a larger frame.
