In most cases I imagine they'll only have one form of metadata coming in and
any other EXR attributes they add will be parsed from that source.
For example, I currently get ICC profiles from the Adobe apps, which I then
parse out to make Chromaticity attributes. But an ICC profile can have
information that can't be reconstructed from chromaticities, so that's why I
embed the whole thing as well.
Anyway, let's not let perfect become the enemy of good. The benefit of getting
more metadata outweighs the risk of getting conflicting metadata, which I would
call a bug for the app developer.
