The solutions from point 1 have a common disadvantage: if a user imports/recovers a BIP<ThisBipNumber>-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-BIP{ThisBipNumber}-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.
