Does go count as managed, in your view? (Honest question - I don't know go well enough to have much of an opinion.)
Using Go as example, and the being in minority remark, you will remember the whole discussion about Go being a systems language or not, and how it was backpedaled to mean distributed systems, not low level OS systems programming.
Now, I remember when programming compilers, linkers, OS daemons/services, IoT devices, firmware was considered actual systems programming.
But since Go isn't bootstraped, TinyGo and TamaGo don't exist, that naturally isn't possible. /s
