Creating barriers or deliberately keeping them up is never the solution. Every time you create more obstacles, you'll end up losing a future contributor or two. Contributors that might end up solving larger future problems or ones that end up owning the whole project after you have moved on. It's not about the slightest inconvenience and obviously you might get slightly larger signal-to-noise ratio but when was the last time keeping into your own small bubble paid off? Most likely never.

At the Brackets project (https://github.com/adobe/brackets) we have seen lots of new active contributors that started from none to giving steady stream of PRs and the effort needed for that was just a slight push to the right direction.
