Suppose I am not a software developer but a system administrator. I prefer not to use the scratch buffer or M-:.

If the variable shell-command-default-error-buffer is not interactive by design, how am I supposed to get a clean output from M-! grub-mkconfig RET, for example?

The design looks inconsistent in that the variable affects only interactive behaviour while being non-interactive itself. What is the use case for it? Who is supposed to modify its value?

It is not intended to be customizable by users. set-variable only
allows you to change values of customizable variables (a.k.a. "user
options"). Use "M-: (setq ...) RET" for the rest.

This is not a bug, but the intended behavior.
