Migration idea: add a "owner_reindex(token_ids: Array)" function (not necessarily owner-only) that will create the missing owner index entries for a list of token IDs. It will also update the supply counter by incrementing it for every previously missing index entry. Ignore already existing index entries.

Then we can just create a script that sends batches of requests to update all token IDs. Note that we probably won't be able to update them all in one request because there are probably just too many domains to fit in the gas limits of a block.

Already updated tokens will be freely usable. Entries that have not been reindexed yet will still be usable for domain resolution and target changes, but any ownership change would result in a failed execution (because the attempt to delete the old owner from the index will fail).

I feel like this would minimize impact.

Of course it will need to be tested in sandbox before we move on to buildinet.
