It is more upfront work for sure. But you get immunity from the planned obsolescence of syntax feature creeps from ISO or gcc extensions (a 5-10 years cycle)...

It is more upfront work for sure. But you get immunity from the planned obsolescence of syntax feature creeps from ISO or gcc extensions (a 5-10 years cycle)... and from compiler implementations. Additionnally, if we are honnest with ourselves for a lot of programs, from a life cycle perspective, coding time of the bulk is actually negligictible. It is not the case with all types of programs though, but for a lot of system programs, this is very true. And rv64 is supposed to become THE ISA standard. One of the main reasons for C existence is ISA abstraction which is kind of gone here. Of course, I wish risc-v to be a success.
