To somewhat counter that, the 6502 could read and write to the first 256 bytes of memory with shorter instructions. The 65816 expanded that idea to allow you to do that to any place in memory.

The Western Design Centre actually describes the 65xx as an addressible register architecture http://www.westerndesigncenter.com/wdc/Presentation_Artwork/... [zipped PPT], and by that I assume they're describing the zero-page addresses as registers.
