Personally I believe that NMM has grown beyond the "Beta" quality and should advance beyond that labelling as beta does get too many negative connotation attached to it these days simply by many sub-standard practices by those who don't actually know what they are really doing thinking they do. However while this is not the case with the NMM developers, and I will take them on their word that it is not yet ready for a letter-less / final / stable release (I haven't looked at the code or the intended features not yet implemented so can't truly judge it accurately). I will state however that there are other alternatives to calling it beta / open beta / etc. which could be considered instead... OK so I know that a lot of very stable and high quality Linux software used in production server environments are still technically beta versions we are however talking about a majority of the NMM users (based off what I have seen from them needing support for the mods), NMM is dealing with non-programmers and a heap of non-tech-savvy windows users.... ...Which means that by marking it as being beyond beta but not yet calling it a final "Final" / "Stable" could increase usage and stop such complaints as mentioned above. So I guess what I am suggesting could be done is calling it a "Release Candidate" (0.xx.xx.xx... rc) or give it a "c" appellation instead of a "b". and then when you finally get the first "final" release (I will happily assume that even after the final release it will continue to be developed and evolve further) so that you can eventually drop the letter on the initial final release only to start them back on the pre-release letters before the next "Final Release". At the end of the day it's your software, and you can choose what you do with it / label it and it really shouldn't matter what other people think or say, and in all honest there is no hard and fast rule on how to do the numbering / lettering process in development, the general guidelines on these do will vary from one developer to another, as well as from one country / region to another and again from each agency / group / company to any other, and what one person calls alpha could be considered a 1.0 release by another.
