That would be in-line with the /etc/X11 tree set in the
long-standing, decade old Linux Filesystem Hierarchy
Standard (FHS) 2.1-2.3 releases, the last of which, version
2.3, was 2004: 
  http://www.pathname.com/fhs/pub/fhs-2.3.html#ETCX11CONFIGURATIONFORTHEXWINDOWS

Neither FHS, nor Linux Standard Base (LSB), seems to define
where the Display Manager (dm) files go, and I don't believe
they have at any time.

In general, when you have these varying changes, it's best
to avoid covering those specifics.  Stick to the generalities
that apply to all.

Just because some distros don't install the X11 Display Manager
(xdm) by default doesn't mean they don't ship it.  E.g., Fedora 9
still ships xorg-x11-xdm, and it's configuration files are in
/etc/X11/xdm.  I looked at the XFree86 and Xorg projects and it
seems they too are still shipping xdm with config files in
/etc/X11/xdm by default.

Please ensure that just because your system doesn't have a path
does not mean it really doesn't exist at all in a package for
your distro, or in the upstream feed.  That is the case with
both XFree86 and Xorg, let alone Fedora.  I bet if I checked
Debian repos, there is a xorg-x11-xdm that is similar.

Although I do agree that specifics on gdm and kdm should be
avoided, since they now vary in many implementations.

P.S.  I have personally implemented xdm in newer distros myself.
Not everyone runs full-blown desktop frameworks -- from servers
to to kiosks to the thin client systems I'm integrating for a
household name corporation.  Even if I run GTK+ or Qt apps, I
often don't install GNOME or KDE when EEPROM space is a premium.
