I'm very surprised to read "However please do not expect ... code reviews, other than for bug fixes." for an open source project that's maintained by the community. Either this is a supported feature and the community should review whatever patches we get for it on their own merits, or we should officially end-of-life this functionality and talk about timelines for removal.

On the one hand, documenting reality is always a good thing. On the other hand, I think this needs community buy-in around what message we want to send users. I've already started seeing off-list complaints about suddenly dropping support for a proven technology in favor of an unproven one, and I share that concern. This isn't to suggest the authors of Centipede shouldn't be working on that project! It's more to point out that saying libFuzzer is supported but not actively worked on may not be the messaging we want to send users (as several folks seem to read this as "not supported" despite the docs saying "fully supported", and there may be community members who want to step up to actively support the project to add new features, minor bug fixes, etc.
