Ameloblastic fibroma

Interestingly, new 2017 WHO/IARC classification refers that ameloblastic fibroma may show formation of dental hard tissue, as ameloblastic fibrodentinoma or ameloblastic fibro-odontomas are no longer part of the odontogenic tumor classification. I reckon (a daring personal opinion) a vast evidence of tumor genetic profiles are needed to separate odontogenic lesions in a new classification or, even worse, eliminate them for good. Opinions?
