If you are not interested in contributions to you project, then you are not the intended audience.
Some thoughts supporting the post:
As a contributor I view my contributions as an investment, if my contribution is likely to help others I will be more motivated to contribute. If unfortunately it looks like my contribution will merely idle, I will consider alternatives. Quick-patch my fork and move on, switch to another project that is well maintained or if the project is critical to my work, I may offer to maintain it.
In addition, I will more likely to go above and beyond in my contribution if the project is well maintained and the likelihood of my work landing in the mainline is high. As a maintainer, a positive correlation exists between active maintenance and community contributions.
