Government organizations do not have unlimited resources, when you ask them to emphasize a new area, it will generally mean taking resources away from an existing task.
And investigating modern child pornography is a very resource intensive task. It involves long term infiltration/hacking of hidden online communities to identify suspects and the suspects have to be investigated and evidence secured. Then when they get the actual child pornography, often sizable "collections" with thousands of items, every picture, frame of video and each sound has to be carefully analyzed to look for clues as to the child and abuser's identity and the time frame and location the abuse happened. And assuming they are successful, the images usually come from a foreign country, which means further time spent coordinating with law enforcement from all over the world making sure they have the evidence they need and that investigation on their end is progressing.
It is slow, complicated and grueling work, and finding officers who both have the technical expertise and stomach for it isn't easy. Burn out rate is also higher than average, meaning new officers are constantly needed. So all things considered, I don't think shoving additional tasks on child pornography investigators is something that should be taken lightly.
