The option is purely temporary and will be removed in the future. I guess it depends on the meaning of the word 'common' in this context, but it enables experimental use of Clang for scalable vectors, which is common if the targets support them. We'd like to remove this flag sooner rather than later, although there is work involved in LLVM before we can remove it.

Are you specifically concerned with the length (as in: number of characters) of the cc1 command?
