Why was Document#_roots made public?

[Reinmar]

I see it was made public in ckeditor/ckeditor5-engine#813. Why? Couldn't it be protected if the dev utils need to access them? Besides, wasn't Document#getRootNames() + Document#getRoot() + Document#graveyard enough?

AFAIR, it was made public during writing logging tools for engine. I noticed that the implementation between ModelDocument and ViewDocument is different. I haven't seen that ModelDocument has getRootNames though.

If that's the case, we can think of unifying the implementations by making _roots private for both model and view document, and introduce getRootNames() for ViewDocument.

I think it's gone now, so closing.
