hey John, In line with the policy we adopted earlier regarding trials in this bucket of features [1], I appreciate the reporting around total page loads.
We're inclined to extend this OT, but wanted to quickly check in to see if y'all have any interim results from the trial thus far. Are you surveying developers? Is there some feedback you could perhaps aggregate to give us a sense for how it's going?
