>I just know a lot of people find side projects fun because they can let loose a bit and try out random stuff that may not be their "best" code.

This is still a huge asset. It's important for a person to want to grow and learn new stuff. When it comes to hiring a person, there's a whole lot of stuff that's important. Maintaining a long lasting project is one of them. Having an interested in fun side projects, also. It doesn't have to be good code. In fact, I have my fair share of "this project is not maintained and should not be used in production code" repositories. That's just shorthand for "this code sucks".
