The pipes, if they hold up during the back fill, would be okay long term (dirt would lock them in place), but yes there is a definite tinge of laziness there. In many ways they look neater than the ones for my pool. You will know they (or redone ones, make sure they repressurize the system if they do redo them!) held up because there should be a delay between the shell of the pool being blasted on and when the plasterers will cut the caps off the returns. If it's holding pressure then, you are good. Check for this yourself.
I will give you a vote of confidence too, so far I really like the in floor cleaner, especially now in the winter because I don't have to remove the solar cover much (only for chemicals and peeking. I did a good brush down twice on a "warm day" and I'll have to do a really good one in the spring, but no biggie.). Everyone seems to have them in Arizona (or at least in Tucson) and I thought I'd probably lose an eventual sale of the house if I didn't do it too. Having said that, in most other places they probably wouldn't work as well. I could see how there would be issues with it in areas with a lot of leaves, branches, grass clipping, etc. In Austin with your lot I think you'll be fine too.
And for the skimmers.. those Paramount skimmers are awesome. I'm sad that Hayward (and the equity fund people) bought Paramount. If it were the other way around the Hayward equipment would improve vastly in quality. Paramount stuff is GOOD!
