Hi Zak, this question is a little out of your scope, but perhaps you may know the answer: Do you know if/when Colab TPU runtimes are likely to be updated to support newer JAX functionality like pjit? (Or put another way: are Colab and Cloud TPU runtimes expected to be in-sync at all?) I'd written some model code that worked great on a TPU-VM and that I was excited to share on Colabs (which is likely far more accessible), but then I found out that Colabs simply don't support pjit (https://github.com/google/jax/issues/8300).

Other than that, really like TRC!
