Also relevant here: B2G. Currently --disable-gmp-sandbox and currently not using media plugins, but that might change.

Jed - Can you take this? Thanks

Should B2G be exempt from this requirement, or will it also need GMP sandboxing? In either case it might make sense to allow GMP sandboxing to remain optional on B2G for now, and then make it mandatory when and if it's all working.

I'm good with going forward in this bug under those assumptions, but before we go too far, we should reach out to B2G folks and cpearce and get their buy-in.
