that's not correct.
an orientation -is- given by the matrix of the parent file.
we just have to state in a comment in the empty file that the stud placeholder's "up" direction as usual is pointing upwards the y axis.
an empty file here clearly can be used for the purpuse of supplying connectivity info.
it even could be scaled to indicate the stud depth/height.
AND
we could introduce many different such files for the many different kinds of connections we have.
we could even put some optional visible contents into them to make them more easily placeable.
we could use the technique of lsynth for that, ie, special meta commands which enclose that file's portion.
