I am struggling with this one since the driver is still adding
attributes manually. You mentioned in the other thread that
"
That's what the is_visible() callback is for in the groups structure,
you determine if the attribute is visable or not at runtime, you don't
rely on the driver itself to add/remove attributes, that does not scale
and again, is racy.
"
I interpret that as "there's still a race here", no?
