My LEAF had that repair done under warranty (cell #17 was dramatically weaker than the rest, resulting in the pack suddenly having around 33% range and 50% power). Repair was disassemble, change module #9 (cells 17&18), reassemble but took about 2 calendar weeks for parts and trained labor reasons (repair itself was done in a single day).
3.25 years later there is no evidence of recurrence/spread and battery diagnostics are all good. That’s an N of 1, but I don’t see any structural reason to think my battery would now be any different than the sibling car’s battery that was next off the production line (assuming there was no additional fault introduced during service).
