This setting is potentially dangerous, as it could hide misconfiguration
errors from users.

What is the default setting? Is it much lower than 1000?

Sage believed the default to be 300 and mentioned that the default is sometimes updated based on real-world user reports/issues. At least that was my understanding.

I am guessing this is failing the integration tests because there is only one osd in the test env that starts with more than 300 pgs. There doesn't seem to be a log from the operator pod in the artifacts, which makes debugging hard. This seems like it may be related to the discussion started with this comment: https://github.com/rook/rook/pull/2470/files#r246889563
