As Lars said, I've been writing EXR files with ICC profiles from After Effects 
and Photoshop for some time.  Code for the custom attribute is here:

https://github.com/fnordware/openexrAE/blob/master/src/OpenEXR_iccProfileAttribute.h


My rationale is simple: I can't prevent users from putting non-linear pixels 
into an EXR file.  The color information I get from these programs is an ICC 
profile, so that's the metadata I store.  (I also do my best to convert the ICC 
info to EXR standard attributes like chroaticity.)
