While I hate to engage in speculation, tell spooky stories, or screech at people about the evil CLA you have to sign in order to contribute, my personal opinion is that if Google were ever to start throwing their weight around, the project would be forked in short order and development would continue as normal – it has momentum, plenty of non-Google contributors, and a community. It's also not a product per se, though as we're about to find out, you can certainly build products on top of it – that probably makes it less likely for its current home to suddenly become proprietorial about it.
(hi Andy!)
There's some legal annoyances around e.g. CLA which was a result of being a side project of Google originally. Hopefully we'll move through that in due time. But realistically it's a much larger project at this point and has grown up a lot, it's not Martin's side project anymore.

I have all of them run `jj status`, because jj snapshots the working copy every time it's invoked.
You can have Claude write the hooks, but mine is:
`[[ -d .jj ]] && jj status >/dev/null 2>&1; exit 0`
You could also turn on watchman and have this property on every save of a file and not even need to worry about hooks.
