Turns out this was quite easy (easier than I'd expected):

    Hybrid hierachy
    
    If a hierarchy block is missing its refdes=... attribute, insert
    it without any hierarchy prefix.
    
    (IE. its contents are instantiated at the same hierarchy level
    as its containing schematic).

diff --git a/gnetlist/src/s_traverse.c b/gnetlist/src/s_traverse.c

       }
       
       if (hierarchy_tag) {


Can anyone think what this breaks?

Should we print a warning to the console when this occurs (in-case
someone just forgot a refdes= attribute?)
