Everything never comes from a single vendor. Even microcontrollers the hardware abstraction layer is hiding peripheral support packages for all the i2c and spi things it talks to, each from a different vendor potentially. I'm not saying we should be running k8 on an 8051 or even a cortex m33, but on an arm7? Maybe. Cult of Ferris time, static linking in rust means your binary is your container, particularly if you statically link in musl.
