For plugins we need the __symbols__ node to support stacked overlays, i.e.
overlays referring label that were introduced by a previous overlay.

Although it is arguably useful to be able to refer to symbols created by
one overlay from within another, do we really want all symbols to be
global? Isn't there a call for a new syntax or usage pattern to indicate
either that a symbol should be local to the overlay or, my preferred
option, global?

So, this is back to a design question about the overlay format.  As
noted in the initial discussions about possible "connector" formats, I
think we will want some sort of local symbols.  But the current
overlay format with all global symbols is out there and we need to
support it.
