It's possible, but since the software is going to be open-source, it would be easy for someone to disable the check.
On the other hand, it's not as if it was the only way to dump Jaguar cartridges : besides desoldering ROMs, there is another (non-invasive) way that I know of. It's more difficult for an average user, but it didn't prevent existing games from being dumped (including those that shouldn't have been, unfortunately). So I think the release of this tool would make little difference for those with dishonest intentions. But I believe it can be helpful for honest people.
