It works well enough that I didn’t realize this wasn’t first party till right now.

It works, but there are fair amount of caveats, especially for someone working on things like Pytorch, the runtime is close but not the same, and its support of certain architectures etc can create annoying bugs.

For me, no. Spend days trying to get it to recreate a production environment workflow. It is too different than production.

it has. it's improved to work with ~ 75% of steps . fast enough to worth trying before push
