RFCs

The RFC process is documented on our site. Please familiarize yourself with it, before working a new RFC.

Status can be one of these values.

Status	Meaning
`UNDER REVIEW`	RFC has been proposed and community is actively debating the design/proposal.
`IN PROGRESS`	The initial phase of implementation is underway.
`ONGOING`	Some or most work has landed; community continues to improve or build follow on phases.
`ABANDONED`	The proposal was not implemented, due to various reasons.
`COMPLETED`	All work is deemed complete.

The list of all RFCs can be found here.
