I think that's natural and OK. I would compare writing my thesis to writing my first full application after learning how to read and write code—even after several iterations under a skilled supervisor, the codebase is still going to have a more or less fledgling and awkward quality to it, even if the functionality proves useful. The second attempt takes less effort and results in higher quality output.

Similar to how few people would put their first application out in public, I prefer to keep my thesis private unless someone finds the information really useful :)
