It can be enlightening to try something new, for example, Rusts borrow checker, containers etc.. But beyond that there's no need to actually code production. Looking at the actual code and observing the process at that level of granularity can be helpful as well. But given the amount of focus, attention, issues around specific compliance, reviews, I'm not sure if it's a good idea for the CTO to be coding when the company has >50 Engineers, they'll probably just be in other people's way. So definitely 'hands on' experimentation, but I don't think it generally would be production coding. That said - there are certain types of execs who really love that, and find extra time to do it, if they want to stay late Wednesday and Thursday nights, then that could work as well.
