You basically demonstrated nobody read my comment in there months ago ;-) https://github.com/zenparsing/es-function-bind/issues/17#issuecomment-120978833
Anyway, the security concern is non existent to me, every method of every instance of every class can be a communication channel, everything bound can be a communication channel, I don't see why ::obj.someMethod would be different and is not explained anywhere in there. But since nobody read that thread anymore, I guess it's pointless to even keep writing in there.
