The Fedora Project has high standards, and our users should expect that when something carries our name, it meets a certain level of reliability, reproducibility, sanity, and elegance. At the same time, two of our basic values are "Features" and "First". Often, emerging features aren't yet reliable. Experimental designs might not be pretty. A little bit of messiness is particularly likely when we aim to integrate these new ideas first.
Fedora Playground is a label for services, offerings, and subproject which are officially part of the Fedora Project as a whole, but which we know are a rough around the edges.
