Atleast I think that was a good move. Since keeping using broken thing is not good at all.
My opinion about CFW: I don't like master race trend in every aspect. Not Just Luma3DS.
It's alway better when people have more choice to pick.
And I don't think we have less CFW cause those Luma3DS master race.
Most people here aren't developer, and most developer may think that the current CFW in the market is enough.
Luma3DS for Noob, SaltFW for people who want less, ReiNAND for people who like µ's, or Corbenik for who want to conquer their 3DS.
And we already have something that can totally replace rxtools, so may be the dev won't see a point to revive it.
