With the inflationary amount of NAM files (and we're likely only at the beginning), this will possibly become the same as it's been with IRs, namely an endless rabbit hole. Which possibly is the positive aspect of proprietary formats a la QC and KPA - you do at least need the hardware, so not every single hack on earth can upload and share their captures of whatever it might be on Tonezone3000.
Also, with the QC and KPA, you can at least kinda access captures more or less straight on the unit, whereas with NAM profiles you have to download them, possibly prelisten to them in whatever NAM plugin (all of them offering no proper onboard database management) and finally transfer them to whatever hardware.
During the time that takes I would've created a dozen gigworthy patches within any decent component modeling hardware.
