Readability at Google suffered from this issue both directly (requiring someone with Readability in a language to review and approve before landing a CL) and indirectly (the backlog of requests to obtain Readability was at one point I think over a year long for some languages).

Contrasted with Facebook where you were expected to commit code to production your first week. I couldn't believe how different the eng cultures were.

(Each has their pros and cons, not saying one's perfect and the other terrible.)
