I haven't seen this mentioned before, but here's a fun bit of DS9 trivia.
The DS9 Promenade set stood in Paramount Stage 17, which from 1959 to 1970 was another home out on the frontier: it was where Bonanza's Ponderosa Ranch interior sets stood.
Stage 16, which was TNG and Voyager's "Planet Hell" set was also used by Bonanza, and contained the Ponderosa Ranch house exterior, barn, bunkhouse and horse corral.
So, I guess the "frontier" tradition stuck with those stages for a long time.
