Because we've found it too noisy. -Wconversion is a super-set of -Wreal-conversion. We added it in response to internal requests. -Wconversion was warning benign cases so we could not enable it by default in our builds. Le-Chun, do you have some examples of -Wconversion being too spammy for us? Diego.
