That is inevitable for any wallet that offers any functionality beyond
just maintaining a balance and the ability to send coins. In
particular, anything that wishes to list previous transaction (with
timestamps, history, metadata, messages sent using the payment
protocol, ...) needs backups.
What HD wallets (or any type of deterministic derivation scheme) offer
is the fact that you can separate secret data and public data. You
only need one safe backup of the master secret key - all the rest can
at most result in privacy loss and not in lost coins.
