Wallets could auto-respend transactions to a plain (private) HD derived key to make them findable again. But that gets us back to using block space inefficiently. Over time I think wallet backups will get more valuable anyway, as they will start containing more and more essential data that isn't in the block chain: receipts, messages, exchange rate records for tax purposes etc. But being able to get access to your money with just the 12 words (+a date for SPV wallets) is a pretty desirable safety feature.
