Agree with you totally there!
However, I have always found it useful to have a debugging version
of the kernel which allows you to use something like gdb to debug
your embedded system through a serial port.

Sadly, the last embedded system I worked on was a TMS9900 some

UART emulation, software modem, embedded control language etc.
