Yes, that's what "man csh" says... but decades ago it didn't
work. I remember that when using xdm with .xsession to launch
the user components of X, whenever I opened a terminal, my
C shell settings from .cshrc (!) weren't included, that's why
I invented the "cascading approach" for .xsession and .xinitrc.
That was a long time ago, but it still works.

I don't know how other display managers handle things. I did
not need that for slim, and I got rid of gdm quite quickly
because it didn't care for _any_ user configuration file (no
.xsession, no .xinitrc, no nothing).

I think the #!/bin/sh in .xinitrc is just for the reader, because
the manual of startx says that it will use /bin/sh for execution
if .xinitrc regardless. However, it's not wrong and it doesn't
do any harm. Similarly, there is no mention that this file has
to be executable (+x attribute set), but again, it's probably
not wronger than the #!/bin/sh line... :-)
