[TheForge] Carbon loss with gas forges

In researching forges to start as an hobby bladesmith, there seems a 
strong bias toward gas forges. The reasons seem fairly transparent, 
cleaner, easier to use, more productive, etc.

My question relates to carbon loss in the steel when being heated, my 
understanding is that carbon burns off and is replenished naturally in a 
coal or charcoal forge. Assuming my understanding is correct, how do gas 
forge users compensate? Or is the carbon loss not significant enough for 
most smiths.
