But Emacs does that for ages, so in Emacs this is veteran behavior of
the default sentinel function.

Actually, it does, albeit in the parent section:
Alternatively, you could use the ‘:stderr’ parameter with a non-‘nil’
value in a call to ‘make-process’ (*note make-process: Asynchronous
Processes.) to make the destination of the error output separate from
the standard output; in that case, Emacs will use pipes for
communicating with the subprocess.
