I always wonder why there has not yet been constructed a mechanism that
automatically pulls in devices that are needed to prevent compile failure.

It wouldn't be too difficult, I assume, to have "device miibus" pulled
in, when needed for certain devices.

Or is there a good reason to allow people to compile, for example
"device rl", without the miibus device?

Having such a mechanism, would prevent lots of beginners in the
kernel compiling stuff, to get frustrated with errors like above.
