To be a little constructive, here's what i think is needed (just my personal view of course):

Don't make a proper install file and the project being in maemo extras a prerequisite. Instead make this the goal. Don't limit the projects in any way, but list them to get people involved. There sure are projects that people love, but that never got an install file or never were properly hildonized. Why don't try to achieve this via this wiki page? Something like "people love project xyz, so we encourage you to make it ready for prime time".

This might even be closer to what you intended to achieve as this might indeed save some nice projects from getting lost.
