If it had been called something like "Paper Mario: The Tribe of Ancients and the Dark Prognosticus", fewer people would've thought it was New Super Mario Bros. and maybe not as many people would've been disappointed. Also if New Super Mario Bros. Wii had already come out in 2006, so that people in 2007 wouldn't be so desperate for a Mario sidescroller. Then the main problem would've been that it's not as fun to not have real party members.
While I liked all the "old stuff" in Super Paper Mario, I'd say it's Nintendo's fault for marketing the game as a platformer like Super Mario Bros. rather than an addition to the Paper Mario series.
Such things are welcome when done right (e.g., when they bring something good to the table of their own (i.e., the opposite of Sonic 4)).
By the way, the opposite of Sonic 4 (at least Episode 1) is Sonic Generations (at least the console version). In fact, in my personal canon, Sonic Advance is Sonic 4 and Sonic Generations is Sonic 5.
