I looked at it and consider the crypto choices reasonable and reusing
existing bitcoin dependencies in library crypto building blocks
mostly.

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.
