From an outside perspective, as someone who does embedded development as a hobby rather than a profession, the answer is both yes and no. The stability of C and C++ helps, but you still have some churn in libraries and you almost certainly have to deal with vendor specific libraries (which makes moving between vendors difficult). Trying to bypass libraries doesn't really help on that front, since you are simply trading of churn in libraries with churn in microcontrollers.
