I already told you what it is, and not to worry about it. There is nothing wrong. It's just a welded on bracket that was designed the way it was for NVH, and/or for specific characteristics in the event of a crash.
I even looked it up on the database. The subframe/ engine cradle/ engine mounts are all viewable.
If that doesn't convince you, I was a Master Tech at a Toyota dealer at one time. I still have friends in that line of work.
As for your '07-'08 looking the same as a '98, there would be some differences, as there was a design change with the '02 model year.
Your Camry is fine.
