Correct, this is at least partly why GN aren't built for
these elements/subtrees.

Batik absolutely does create GN for elements that only have
'visibility:hidden'. I know that because we have tests to ensure
that pointer/key events get sent to those elements.

It would seem so. Can you post an example of the SVG document
you are trying to work with, along with the code you are using?
I feel I should also mention that I have yet to encounter anyone
that has tried to manipulate the GVT tree directly that wouldn't have
been better off manipulating the DOM. So you might want to rethink or
ask about why you need access to the GN's at all. Your stated reason
doesn't seem to rise to the level needed, you can easily toggle the
visibility of nodes through the DOM.
