Hello @DanielRosenwasser
Can I open a pr for this? I don't see a "Help wanted" tag

[jakebailey]

The automation rejects PRs to the generated libs from outside contributors, so unfortunately no. (It does that because most PRs people send are in error not realizing they are generated from the other repo.)

We'll keep it in sync.

Okay
