Yes, embedded development has always been stuck in the stone age. C is actually a recent, and major advance over assembly. It happened only because vendors discovered they could steal accounts from competitors by being source-compatible, even though their ISA was different. C++ does not offer that advantage for them, no matter how much it might benefit developers, so they have no intention of ever supporting it.

But Arduinos are programmed in a dialect of C++, so it will become necessary to enable it in the near future, i.e. by 2030. Civilization might fall first.
