Is there anything in the Star Wars canon that explains the alarming lack of safety railings on various structures in the Republic? An example from The Empire Strikes Back, a landing pad on Bespin:

The ankle level curb might be considered a weak nod toward safety but I would not want to be on that platform if winds were high. Given that Bespin is a city in the clouds, winds would be high a lot of the time.

There are other examples, such as the open catwalks over an abyss in the first Death Star, the balconies on Coruscant, open staircases everywhere, and the catwalks on which Qui-Gon, Obi-Wan and Darth Maul fought on Naboo. There are some exceptions, too. The Ewoks believed in safety apparently and used railings on the catwalks between their tree dwellings. On Bespin in the lower level where Vader and Luke fought there is a railing on the gantry stretching over the abyss.

No note is made note of this situation in the movies, but there is much more Star Wars related material than I will ever see or read. Does any of it address the railings issue?
