optional: It seems good to have Nacl in the name: kAllowNaclFileIOPrivateAPI

Hmm actually, I intentionally removed NaCl from this name. I think our
out-of-process version (non NaCl version), which is being used for development,
can also use this. Also, browser_tests are using this to test out-of-process
test.
