The problem seems fixed.
Assigning to the author of the reverted CL.

Ned, can you help me figure out what step I'm missing when deleting the benchmark? I ran generate_perf_sharding and generate_perf_data for the CL before landing.

Alternately, can I just assign ownership to you as originally planned so that you can take on cleaning up the benchmark?

#4: can you assign ownership to Ben or Sean instead?

It appears that the reland has stuck, so I'm going to go ahead and close this. Thanks Ned for relanding.
