insertAt shadow root?

[am80l]

I'm curious if this community has given any thought to use cases involving shadow elements.

What I'm envisioning is a capability that would allow you to inject styles into a shadow root, as opposed to just the head of the document, thereby preserving encapsulation for a given component.

I am admittedly new to web components, but using css loader to inject encapsulated styles into shadow elements just sounds like an awesome capability :)

Anyone given thought to this use case?

Thanks!

I need this myself, and I'm working on a solution using a new option called insertInto, which will take a CSS selector to call document.querySelector with. This could allow you to insert the styles into the ShadowDOM using a #host::shadow #someElement-selector, if it exits prior to style-loader running (which is the part I'm having trouble with).
