Isn’t the water in sprinkler systems a stagnant mess too?

Yes. A combination of rust, thread cutting oil, and water that has been in the pipes often since the system was filled. It smells, it will stain anything it touches, and it's a smell that's difficult to remove.

Not true everywhere. Many buildings, especially industrial, require a flush of the fire suppression system annually or biannually to test that everything is still functional.

That's to test the incoming main, the actual grid on the floor doesn't get flushed. There's a lot of dead end pipes that can't be flushed.

Dry pipe systems are a thing. But not very common from my limited understanding.
