I did a bisect based on the runtime of `./gradlew :sdks:python:test-suites:tox:py2:testPy2Gcp` around the commits between 9/1 and 9/15 to see if I could find the source of the spike that happened around 9/6. It looks like it was due to PR#9283 [1]. I thought maybe this search would reveal some mis-guided configuration change, but as far as I can tell 9283 just added a well-tested feature. I don't think there's anything to learn from that... I just wanted to circle back about it in case others are curious about that spike.
I'm +1 on bumping some FnApiRunner configurations.
