I think that for all four of these characters it is fairly obvious that they are necessary for correct grammar, specifically:

Previously we also had this comment:

My interpretation would be that Greek Final Sigma is necessary for correct spelling of Greek, and that it is common for Greek to be entered with and without the Tonos.  So it seems likely that when uppercase forms are used users likely expect several possible values to lead to the correct site.  As the NICs reported about Final Sigma, it seems clear that users would also expect the correct site to have the correct spelling, even if the user had ignored the Tonos "for comfort of typing".  

So I think further discussion is interesting because, while we have clearly determined that Greek Final Sigma is required for the correct spelling of a site's name, we haven't necessarily determined how what combinations users may enter to get to that site.
