@kalman, 
Can you help me to take a look at the following files?
native_message_host_chromeos.cc
extensions/common/switches.cc
extensions/common/switches.h

I mainly remove the flag in native_message_host_chromeos.cc. I know that
sergeyu@ is probably the best person to review the change but unfortunately he
is on paternity leave.

@Alexei,
Can you help me to take a look at the following file?
tools/metrics/histograms/histograms.xml

Keep the entry here, since its used to decode data from old versions.
