Well, none of these projects except for one (Taiwan) seems to export stats, so it is close to obsolete to include them.
Besides, QCN itself is going to be retired since it isn't maintained as usual anymore, and these are only "supporting" or subprojects of the main one AFAIK.

But in any case is better to make a list of ALL projects on boincstats, even those who do not export statistics (at least not for statistics, but simply to take part in the computing).

QCN is not being retired due to it having renewed life. However, the "sister projects" are no longer funded and are basically just floating on their own. So, they probably won't have the continued support that QCN is being promised. That has all been reported in QCN's forums just recently.
