Which claim?
That only long CV lenses for FF have ever been branded APO?
Just look at their history. Maybe there are some post Cosina lenses for ff branded APO that i dont know about, but as far as I know there are only, before this new one, the 90, 125 and 180 APO lanthars.
The other claim was that the 1.7/35 was more or less APO. Now the problem with that claim of course is that there is no agreed definition of how exactly the different colours have to focus in the same plane to count as apochromatic; its only ever meant 'less LoCA and LaCA and SLoCA than comparable lenses". But the 1.7/35 has less visible CA than the APO lanthar 180, which is nonetheless pretty good.
I think historically APO stickers appear on long lenses more often just because, until recently, chromatic abberations were worse in many longer lenses and people wanted to know they had been mitigated.
