> Portability was always a selling point of C++.
Judging by the lack of modern C++ in these crufty embedded compilers, maybe modern C++ is throwing too much good effort after bad. C++03 isn't going away, and it's not like these compilers always stuck to the standard anyway in terms of runtime type information, exceptions, and full template support.
Besides, I would argue that the selling point of C++ wasn't portability per se, but the fact that it was largely compatible with existing C codebases. It was embrace, extend, extinguish in language form.

Being conservative with features and deliberately not implementing them are two different thing. Some embedded compilers go through certification, to be allowed to be used producing mission critical software. Chasing features is prohibitively expensive, for no obvious benefit. I'd bet in 2030s most embedded compiler would support C++ 14 or even 17. Good enough for me.
