if it is excessive to align textures on a face of a prim that 1. is not exposed, 2. will be underwater and 3. will be under the terrain
well, at least if anyone ever cams down to the underside of the pool, it will be pretty

attention to detail totally rocks! 
I would do it.
I agree... I've been known to cam inside chimneys.
i kind of hate when i cam into a building and see the backsides of walls (that are not visible usually) covered in building grid. 
Not excessive. As things rezz, sometimes you see the innards. Why not let them not distract as they build?
good, I am reassured, lol
