The solutions from point 1 have a common disadvantage: if a user imports/recovers a BIP49-compatible wallet masterseed into/in a non-BIP{ThisBipNumber}-compatible wallet, the account might show up but also it might miss some UTXOs. The solutions from point 1 have a common disadvantage: if a user imports/recovers a BIP49-compatible wallet masterseed into/in a non-BIP49-compatible wallet, the account might show up but also it might miss some UTXOs.
Therefore this BIP uses solution 2, which fails in a more visible way. Either the account shows up or not at all. The user does not have to check his balance after using the same seed in different wallets. Therefore this BIP uses solution 2, which fails in a more visible way.
