[Framework7 v6] f7params not extendable?

hi @nolimits4web on version 6 the f7params is not extendable? is it no longer support?

const f7params = {
name: 'MYAPP', // App name
theme: 'ios', // Automatic theme detection
id: 'my.app', // App bundle ID,
myCustomProp: 'hello'

}

myCustomProp will never be extended to f7Params or passedParams property. I need to access my custom params from my plugin

Thank you
