The answer is: 1. gcc will still be available through the ports system. 2. The move to clang/llvm as a default compiler will reduce the amount of GPL code in the base system, eventually reducing distribution issues (especially for 3rd parties). 3. clang/llvm provides better error and warning messages, as well as good static code analysis, which helps reduce some classes of bugs and eventually will result in a more reliable FreeBSD system. 4. clang/llvm is improving quickly. 5. clang/llvm is more modular than gcc, although there are plans for gcc to become as modular, it will take time. 6. gcc produces faster code, but clang/llvm will eventually (soon enough) get there. 7. From the reasons above, it makes sense to complete a task sooner rather than later, especially that clang/llvm isn't showing any signs of weakness (lack of development power, etc). 8. There might be more reasons for or against, but I couldn't think of any.
