Why does tonemapped EXRs get clamped?

I just noticed something that I wasn't aware of:
Tonemapped EXRs get clamped! Its like 8bit information only written in a 32bit file!
Isn't it possible to apply tonemapping without clamping all the extra informations?!
Indigos (camera) tonemapping is very well suited to achive a good look and a great start for doing final corrections etc.
But by dismissing all the extra image information we are forced to go for the untonemapped version...
Here are two example images (rendered using linear tonemapping @ 1), I just loaded both EXRs back into Indigo GUI:
