I've literally *never* heard them say that Btrfs isn't ready. However, they have told me in the past to be cautious with some features for "enterprise supportability".

I'm pretty sure this is another variation of the "shutdowns" I keep getting when trying to work on Btrfs support in Fedora. It's surprisingly annoying that Fedora as a community distribution has touch points where community members have basically zero chance at being successful at anything. Honestly, I'm surprised we've kept Anaconda as the installer for Fedora, given the attitude I and other community members get from the Anaconda developers and sheer amount of pain and agony we have to deal with to even attempt simple contributions, much less complex ones. Amazingly, I do have a single commit in Anaconda[0], but the amount of effort and time it took to get it in was ridiculous. And while I like the Anaconda installer, I don't like that there can never be a community around it. It's one of those projects that has a stranglehold around it that is designed to discourage you. And that's not even with things like Btrfs. There's been a request (with code even!) from the Qubes OS folks to add GPG key support to kickstart[1] and Anaconda[2] for literally years. I've wanted to accept the changes for livecd-tools[3] for years, but I can't until pykickstart and anaconda support it. I'm not even going to get into the repo --priority option from the FedBerry guys. By any meaningful measure, Anaconda has less community than Btrfs, and it remains the "blessed" installer. Moreover, it gets to singlehandedly dictate what the distribution supports. And its developers basically get to shut down any discussion of anything related to Btrfs, in any form or fashion[4]. And you wonder why Btrfs support is so weak in Fedora? Because of all this, I was discouraged from finishing and submitting my change proposal to fully enable Btrfs with full system snapshots[5]. I'm honestly not surprised that Josef gave up. I'm surprised that I'm still stubborn enough to try to make it happen, but perhaps there's a part of me that hates giving up...
