Good point, though both xv and netpbm are in wide use, and *would* get maintenance if they actually needed it. I suspect the major reason they aren't being actively maintained is that they are incredibly solid and stable, and haven't needed it.
Xv is a shareware package which requires (expects) registration with a registration fee. Typically shareware packages don't get much support from the open source community. Nothing has happened with netpbm in years. Its bits are slowly rotting.
