I have some decent ideas as to why, I’m asking mainly as a hopefully fun contribution here, and to maybe learn some interesting plumbing info!

While I’m not a plumber there is something to consider as well.
Water hammering
I think this is why something like Pex works well since it’s flexible while not being so flexible that you’d have to worry about long term abrasion and wearing away from a hose bouncing back and forth from it.
Pex is also resistant to bursting in the event of freezing. I used pex in my van build and the few times the pipes have frozen haven’t resulted in any issues other than having to wait for the pipes to thaw.
