Well, mostly because you often get issues where you, as a team, have to make a decision.

Do we decide to support this specific feature, even if it increases our maintenance cost by a lot?

There are many projects. A good way to start is by trying to fix some tiny things that annoy you personally, use your changes yourself, and try to get them merged. This is useful as (a) probably others had the same issues, and (b) you have already tested the changes somewhat by that point.
