One reason for depriorizing it might be that they realized iGPU performance isn't as relevant as they hoped in recent history. AMD spent years betting heavily on concepts like the APU, HSA, tight coupling with coherent virtual memory access from GPU and CPU side etc. They tried to do a "build it and they will come" but the software didn't come and Intel ate their lunch with low effort iGPUs. Advances of GPU programming slowed industry wide, especially software & dev experience / programming language wise, and the GPU world remained far from CPU programming productivity. (And you can still get 2 orders of magnitude of parallelism staying on the CPU, from SIMD, multicore and SMT). They learned their lesson, and this time around came back with a product that can beat Intel in their own game.
