I've not seen that done. On anything I've done, it's the flashing
HOLE that's adjusted, the stove pipe just goes straight through the
roof vertically. And for sheetmetal vents like on driers and hot
water heaters there are elbows with movable segments to get the
desired angle by rotating one or more of them.

If it's just a stub for an attic vent, who cares if it's square or
angled? You're not going to see it anyway and angling the bottom will
make sticking some kind of cap and/or screen on there a lot more
complicated than it needs to be. Unless you live where there's no cold
weather and no bugs, you're going to need one or the other or both.
