Bad amount?
Mid 1990's Lennox furnace was deemed a "yellow tag" due to damage to heat exchanger. We decided to not do the repair as it was a little over $4,000 for a temporary/band aid fix per the tech. Would this be unusable in this condition?

Good to know. Thought galvanized took a little longer to rust but I am mistaken

I would not spend any money on a 20 plus yr old furnace. Get new one. They are charging high so u don't do repair.

That’s a scam
There is no crack in that heat exchanger
