Exactly! What would really be great is if all signers (including hot wallets) would provide an embedded tool to accept a 12th (or 24th) word you generated (likely not checksum-valid), discard the invalid checksum bits, and replace them with a valid checksum and tell you what your new valid last word should be (and force you to reenter your entire seed phrase again for checksum verification) Instead, it would seem most developers are more interested in abstracting away user responsibility for the sake of quick and convenient on-boarding of the naive.
