So it really depends upon what you want out of your research career. Part of being a successful researcher is making an impact on the community. This involves producing works that the community finds useful. I've always looked at making my code available as another avenue to help increase the impact of my work. In my case, many more people have used my public codes than have ever read my papers. You have limited time. I'd prioritize that time on what you think others will find useful. Don't worry about ugly code. There are research codes with 1k+ stars on GitHub that are ugly. They have so many stars because people find them useful. You absolutely don't have to publish your code, or anything else of that matter. Don't let the the drive for impact on the community force you into working on something you're not interested in. Congrats on your publication.
