The only negative side effect is with the Ai. It doesn't break the Ai paths or anything, but this is an action that the Ai can not imitate. This gives the player a distinct advantage over the Ai.
The stairs were making a chokepoint that was too narrow, the player could easily be trapped at wither side with no hope for escape.
The two designs functioned similarly but the paths were an issue for the Ai. I decided to got with a combination of ramps and stairs.
