If Michael is not ging to support it in remote i must agree with you
and say that is not important.

Honestly, not often.

We might modify the doc strings for shell-comamand and 
async-shell-command, following part:
-----
In Elisp, you will often be better served by calling ‘start-process’
directly, since it offers more control and does not impose the use of a
shell (with its need to quote arguments).
-----

I understand what Stefan means here with more control, but someone may 
argue that s-c and a-s-c allow the possibility to separate stdout from
stderr, which s-p does not.  That sounds like less control, at least
with respect the output.
