The question pertained to the Newest USAF F-16's not to the most of the USAF's F-16's.
From the article.
"Over 250 of these aircraft are Block 50/52 F-16CJs that were delivered optimized for CFTs. In other words, around 30 percent of the USAF most advanced and youngest F-16s could easily be fitted with CFTs"
Seems fitting the 250+ with CFT's would be smart.
Having CFT’s PLUS air refueling would give F-16’s longer range, longer loiter time, and allow tankers to stay further back from the fighting.
