In perspective We can set a DOMID to any component, it would be awesome to have something like

document.getElementByID("MyId").props.text = "Foo and Bar"

instead of

self.parent.getChild("FlexContainer").getChild("MyId").props.text = "Foo and Bar"

this will allow not to depend on component messaging to accomplish the goal of decoupling and shorten the development time.

it will not be too efficient ( https://forum.inductiveautomation.com/t/select-elements-components-from-id-instead-of-hierarchical/82851/2?u=subin_adhikari ) but it certainly decreases the dev time.
