I wanted Fable in order to harden my C project against exploits and vulnerabilities. Anthropic downgraded me to Opus 4.8 every single time I tried to do it.

So I don't even know if I miss it. I suppose that's equivalent to never having used Fable at all.

Claude has been doing this to me even without Fable, trying to write a Xaw frontend for the moc music player.
