The "notch" seems fairly common in my limited experience. I remember a few examples that had such a structure but most were broken if I recall correctly. If these are fragile, then they may be lost over time which could account for not seeing them very often.

Posted below are pictures from the web which show such a structure on what appear to be old and more recent examples.
