I'm pretty sure we'll want to have this for devtools and such.
Priority: -- → P2
Addons will need something like this too, otherwise websites would be able to hide pretty much all their content from addons. Addons would be forced to do some xray dances on document_start to intercept every |attachShadow| call and then implement custom shadow tree traversal over the intercepted roots if they wanted to handle with that. If mozilla plans to use shadow dom for internal components too and those are not intended to by accessed by extensions then there might be a need for a 3-tier distinction: - open - closed (accessible by extensions) - closed-chrome (only accessible by system principal) Or maybe this can be covered by giving internal shadow trees different node principals than content-created shadow trees.
We may want to do something more complicated for extensions, but for now, just this simple thing.
