It'd be great to have support for it. Seems Nether Brick Chests already spawn there, but I liked having the gold bars be the windows instead of nether brick fences in normal fortresses. Would be cool to see it in these ones too.

They could replace nether brick fences in the little treasure rooms too (the ones with flat item frames holding loot) (or really just anywhere that isn't a walkway where you'd want fencing).

Agreed!

Also agreed!
