The *encoding* changes. The decoding stays consistent:
> Decoding IDs will usually produce some kind of numeric output, but that doesn't necessarily mean that the ID is canonical. To check that the ID is valid, you can re-encode decoded numbers and check that the ID matches.
The reason this is not done automatically is that if the default blocklist changes in the future, we don't want to automatically invalidate the ID that has been generated in the past and might now be matching a new blocklist word.
