But since nobody but Mullibok made any use of that moon anyway, why not
wreck it? Habitable worlds are a dime in a dozen in the immediate vicinity of DS9 (say, "Sanctuary"), yet Bajorans aren't interested in those, either. Heck, they don't even bother to inhabit all parts of their own planet yet (again, "Sanctuary").
Wrecking Jerrado still leaves four other moons as natural preserves or amusement parks or inspiration for space poets or whatnot. Or perhaps Bajor will eventually have the time and resources to remove vegetation and animal life from those, too, for the sake of preservation, as lifelessness no doubt is the most natural state of those moons!
