I think debuted is singularly infelicitous, mostly because of the pronunciation issue – is it debutted, daybood, debood, daybutted? Made his début’ seems the best way out to me.
These days, I have lost the "y" in daybyoo, and now pronounce it dayboo, as do the French who don't do that thing with the letter u. I'm sure someone has had a go at me for my resistance to verbing in the past (poss. CdM?) but I still resist it where possible.
