Its SO simple you answerd your own question. it is a HEAT SHIELD. it helps absorb and reflect heat away from the cab and well the drive shaft is right above it
disadvantages: increased floor/cab temps (could be useful in the winter) possible melting of things that were once hidden (doubtful though)
I fixed mine with 4 metal screws and air powered drill, even easier than taking it all off!
