Although coming from the microcontroller world there is practically nothing in the STL which gives me the guarantees I need to use it in ISRs and most devs have no chance at reviewing the STL piece to see if its going to deadlock in ISR or something.
Another problem is that although the abstraction compiles away in release mode the debug build usually still has to fit on the chip and/or meet realtime deadlines. Tooling is still super bad at optimizing part of a build and not other parts even though we have an optimize pragma (I brought this up in the SG14 working group but concluded that its more of a tooling than a language issue).
In short I think at least the drivers should be written in C++ with proper abstraction but for the most part those abstractions have not been written yet and we can't just borrow from other domains because we have to be deterministic in timing and RAM use and also usually use other threading models (RTC event based) and memory management models (pools, state local storage) at least in drivers.
