I didn't know about this stackoverflow info. Thanks for that good info.
Yes, waves devs can't help you out if you lose seed for your wallet. They actually give that warning message when you open a new wallet. The best way is you always write down or take a print out and store in few safe locations. If can't restore cache then mostly all waves are gone forever.
