ens eth name

I am seeing conflicting information regarding eth ens names.

When you purchase a name is it permanently tied to the wallet address that purchased the name.

It was reported in the past that you don't lose the eth spent on the name, it reverts back to the wallet once the name is given up (don't know if thats true as it was reported in 2017 and I see no mention of it since)

What happens if your address is compromised? Addresses are pretty disposable and sometimes wallets get hacked and you have to dispose of them, that means the name associated with it is useless. Actually worse than useless as people may still send eth to that name and address...
