Also I would like to say that I was not aware of this mechanism until today, even though I am pretty familiar with the build infrastructure.
I had to remind myself as well, that is one of reason to post this here...

Is there some special reason to limit uppsrce to certain packages?
Well, to keep some 'legacy' packages out of releases, while having them there to support legacy code.
Seriously, it is more about some original projects using U++ (mine and Tom's) than anything else. I have even created 'uppsrc2' with intention to gradually move them there, but it takes time...
