It seems like certain features are available via chrome policies. On Windows these would be set in the registry.
Specifically I'd like to set these two.

I think these were previously enabled via field trials, but I don't think that works any more. If a command line option is available that would be ideal, but it doesn't look like the policy settings can be set via a command line option.
