What's the 'Gamma hack' in GIMP master?

Hi,

the dialog boxes of GEGL based operations in GIMP master have a checkbox 'Gamma hack (please ignore)". What's this?
Why should a user ignore it?

Thank you in advance for your replies

Sven

Brief and precise :-)
I thought the format casts are done automatically?
