Let's do the math. If each Wayland implementation supports an independent 95% of what users need, then:

* With 0 implementations, Wayland is good for 100.0% of users

* With 1 implementations, Wayland is good for 95.0% of users

* With 2 implementations, Wayland is good for 90.2% of users

* With 3 implementations, Wayland is good for 85.7% of users

* With 4 implementations, Wayland is good for 81.5% of users

* With 5 implementations, Wayland is good for 77.4% of users

* With 6 implementations, Wayland is good for 73.5% of users

* With 7 implementations, Wayland is good for 69.8% of users

* With 8 implementations, Wayland is good for 66.3% of users

* With 9 implementations, Wayland is good for 63.0% of users

* With 10 implementations, Wayland is good for 59.9% of users
