:I agree that there might be a problem  however, I generally agree with the changes made since Nov./05 and still do.  Moreover, your above analysis et al. is not necessarily agreeable and glazes over usage of the term, which is no less valid or verifiable, that might differ from cited definitions which seem (IMO) incomplete and minimalist.  For instance, an online search will reveal a number of instances of "single(-)star system" and I think it somewhat difficult to demonstrate they they too are incorrect.  Even if those are discarded, applying this notion merely to systems with two or more stars (double, trinary) to the exclusion of single-star entities (e.g., the Solar System) seems rather illogical.  Alternatively, the current article and definition/content is neither beyond the scope of the topic nor inaccurate.

Thus, I defer to my prior comments: until there is overwhelming evidence to support this position (and I yet do not see it) or additional editorial comment, I see little reason to change the status quo.
