For myself i think the use-case of having an offline seed manager that can be backed up once, and support multiple wallets, including ones created after the backup improves a practical and under-addressed problem for many users and businesses. The fact that the interface between an offline seed manager and a hardware or software wallet can be a bip39 mnemonic seed is convenient and an improvement over using custom derivation paths for practical use given the complexity of custom paths and variable support for them in wallets.
