Yep. And as you stated, it is important to stay as much as possible close to c89, because ISO is literaly doing planned obsolescence, but on a long time cycle (5-10 years). Hopefully risc-v will be a success, and all system components and interpreters of very-high-level languages will be rewritten in risc-v assembly and it will become actually very hard to do planned-obsolescence.
