Maybe I'm going a bit offtopic. Sorry for that.

Importing a bip32 wallet (bip44 or not) is still an expert job IMO.
Also importing can lead to bad security practice (especially without a
sweep).

Users will send around xpriv or import an seed over a compromised
computer to a cold storage, etc.

I don't think users want to import private keys.
They probably want to import the transaction history and send all funds
covered by that seed to a new wallet.

I often though that task is better covered by a little GUI tool or
cli-app/script:
-> Accept different bip32 schematics (bip32 native, bip44, etc.)
-> Accept different bip39 (like) implementation
-> Create large lookup windows
-> Create a sweep transaction to a new address/wallet and sign/broadcast it.
-> Export transaction history (CSV)

But maybe I'm over-complicating things.
