| * Generated seed depends on the wordlist used for the mnemonic. Because | ||
| the "mnemonic to seed" process uses the mnemonic sentence directly | ||
| rather than the original entropy, translating the mnemonic to a | ||
| different wordlist necessary creates a completely different seed. |

Maybe I'd add that this shortcoming has been addressed by wallets by not-allowing generating seeds in other languages than English to maximize compatibility across wallets.

Never attempting to translate to a different wordlist avoids the problem, sure, but it's still a shortcoming given the BIP includes 10 different wordlists. It's your doc, so happy to reword if you prefer, but I think "despite supporting different languages, you can't actually translate mnemonics" is a real shortcoming.
| * No versioning scheme. When originally introduced, there was no way to | ||
| distinguish the address format that should be used for a BIP-0039 key. | ||
| This is now largely mitigated by using descriptor wallets (BIP-0380) | ||
| in addition to a seed however. |

I still do think this is a feature not bug, allowing the seed to be future proof which has proven to be very useful.

Any suggestion for rewording it?
