as somebody who programmed my own game out of nearly 20,000 lines of pure assembly and wrote other tools in java to assist in level creation, i'm strictly opposed to requiring an NESMaker label.
let's allow games to stand on their own merits.
that said, i think if somebody takes the time to make an incredible NESMaker game, then advertising it as such would be a good thing - both for the NESMaker community, and to show the rest of us what can be done with it.
somewhere along the line, making an NES game by yourself is basically impossible - you're going to use a compiler that somebody else made, an emulator that somebody else made, probably famitracker and an NES audio engine like famitone or GGSound, etc etc. literally nobody has ever done all of this stuff on their own. nobody.
so instead of creating divisions and castes of developers, i suggest we look at a developer's output and just judge its value on gameplay and other tangibles. we are, all of us, standing on the shoulders of giants to make this hobby a real possibility.
EDIT - i would just like to add, i didn't always feel this way - i was really concerned when NESMaker came out that shovelware would flood the scene and that by the time project blue was released people would be over the idea of new NES games. honestly i feel like i was completely wrong about that - instead a year later i feel like NESMaker has done a lot to invigorate the scene and you can see that just in the kickstarter returns for various projects - things are trending upwards, not downwards.
