Leo develops rapidly and changes to the language need to be stated clearly and presented to everyone. RFC is the perfect tool for turning chaos into order.
New RFCs should be submitted as PRs into the Leo repository. PRs should be correctly labeled for easier search. Yet they should not have a number unless the PR is accepted by leo maintainers.
RFCs may propose changes affecting multiple systems or projects. They also introduce new changes to the language design or structure. Because of that they should be watched more carefully by as many involved team members as possible. Increasing number of required approvals should help achieve this goal.
