If windows were that much a hazard, they wouldn’t be on any starship, especially not those from the Klingons or Jem Hadar or paranoid peoples like the Romulans, Breen, or Devore Imperium.Those would work better as cargo hatches than the big-ass "Shoot Here for Explosive Decompression" windows,
The windows are fine. The arboretums are fine. Especially if you’re going to be stuck on a tin can in empty space for 5 year missions. We need to take the phaser out of our underwear and get back to living our lives.
