Nah. Its far better that they aren't souping this up by forcibly trying to make it low RCS. Its far better to complete these projects within the set timeline without any delays. That will allow us to overcome the psychological barrier of previous generation projects like Tejas, Arjun, etc. That punctures the foreign arms industry propaganda that Indian weapons projects are slow. I am very happy with the speed of these new projects: LUH, Tejas Mk2, Uttam Mk2, etc being on time. Now watch as the propaganda shifts to "India still making 4th gen planes in 2020s and 2030s".
From a tactical standpoint, low RCS won't offer us a lot of advantages. Stealth is a game of either going all in or simply abandoning it altogether. Its better to have drones and fighters like AMCA that focus entirely on microwave and IIR stealth while also having a 4th Gen fleet that is purely focused on minimizing turn-around time and maintenance costs while maximimizing aerodynamic performance, range, sensors and payload without being dragged down by stealth shaping and materials.
