center tapped transformers

There is a question I asked myself over and over again since the 
first time I've seen a schematic for a Tesla coil on the net: Why do 
coilers ground the center tap of the secondary of the high voltage 
transformer (NST or OBIT) instead of just doing the opposite 
(insulating the case from ground very carefully or cut the connection 
of the secondary to the case)? As far as I know this would be safer 
since touching one of the output wires (or being accidently connected 
to one by a streamer) wouldn't electrocute you in this case since the 
output terminals weren't hot in respect to ground.
