Make .dmrc follow XDG base directory specification

[TLATER]

One of my personal pet peeves is applications cluttering my home directory - every once in a while I try uncluttering it to see just how far I can get.

This time .dmrc is on my hit list. Could it be read from ${XDG_CONFIG_HOME:-$HOME/.config}/lightdm/dmrc, following the XDG base directory specification, or at least be configurable in some way?

Additionally the /etc/lightdm/Xession hardcodes to look in $HOME instead of $HOME/.config.

Please make it configurable via lightdm.conf, allowing the variables $HOME and $USER. So everybody can choose:

$HOME/.dmrc
# present default

$HOME/.config/dmrc
# don't clutter my top level home

/notencrypted/$USER/.dmrc
# a possibility for users with encrypted homes_

None
# use AccountsService only

and perhaps even:

+/path/to/a/script
# this script interacts with, e.g. LDAP. It is called either with one argument 'user' and returns 'session' or it is called with two arguments 'user' and 'session' and stores this info

Not sure if this is the right place to ask, but is there a solution to this? I thought maybe moving .dmrc and chaning sessions-directory in lightdm.conf to the new path, but I can't find any documentation about .dmrc or the sessions-directory option.
