I don't think you started a trend so much, and I agree, I hope it stops here. We have three main "versions" of ReiNand (Cosmo was for your personal use, if I'm not mistaken, so that's why I said three): the original, which focuses more on emuNAND, AuReiNand, which tries to cater to both sysNAND and emuNAND users, as well as have lots of extras, and this one, which focuses on sysNAND exclusively. If I still had reason for emuNAND, I would've just stuck with the original. Since that's not the case, I initially took ReiNand and made it sysNAND only, but then I added a few other things I really liked from AuReiNand.
My intention was never to fragment anything or to fuel a trend. I just wanted to share what I found to be the most useful for my particular setup and desires. Now that we have one for emuNAND (vanilla/original ReiNand), one for sysNAND (mine), and one that does both with lots of features (AuRei), in theory there shouldn't be much of a need to fork Reinand any further.
