The following link shows how Saudi Arabia's government today:
1- Placed satan's obelisk on Mouth Arafat.



There is no harm putting an obelisk on top of mountain. As
130 years ago, there are other structures on top of mountain e.g possibly watchtower/obelisk. And if there is harm onto faith, then the
Wahhabis will be the first to riot about it as
they are the strictest practitioner of hadith.
There's a rumour that Wahhabis wanted to demolish the graveyard of Prophet and companions and relocate their bodies to some other location as
they interpret hadith strictly on not having grave as mosque. They were stopped by Turkey somehow. This might just be a myth , unsure if its hold any truth.
As for innovating new structures like extending walls and making double storey tawaf routes. These actions do not put harm on faith.
