Exactly how much of an issue is decarburisation?
I would guess that when heating the steel, only the very top layer of the steel would be decarburised. Unless the carbon somehow migrates to the surface of the blade from the very center, surely the decarburisation will be localised to the surface steel which will all be ground off anyway?
Also, if you keep the steel in a neutral portion of the fire, in between the decarburising and carburising layers, surely any damage to the steel would be minimal.

Unless you are burning the crap out of the steel, not much at all, just remember to compensate for it, leave things a bit thick but not more so than you regularly would. A funny thing that usually happens is after ht and final grinding you forget to take off a bit of the edge, so there is still a bit left on so the steel might not seem to take as good an edge the first time, that is pretty bad decarb though.

Hence the expression, forge it thick, grind it thin. I can't imagine that that sort of decarb would occur readily with HTing temperatures...

You only got half of the saying "if a blade you hope to win, forge it thick and grind it thin"
