Here is an example that should be pretty familiar. When you have an auto-vectorizing compiler and it generates AVX instructions then you will have to recompile your program when AVX2 or AVX512 are out.
With EPIC this problem is extended across the entire program. The ADD instruction is twice as fast? You now have to recompile everything to use ADDv2.
