Okay, something I can speak too! (Though I left in 2009 but it's close enough) I was a SRE on Gmail, and I can assure you that the experience for devs was not great intentionally.

I made sure those where always on our worst clusters (slowest CPUs and disks) so the dev experience was always the worst case scenario for performance. :-)
