Two comments:

1) people should fix 'make' to just allow `-j` without an argument
(seriously, dude ;^) )

2) You can already do many of these things, and I've sent various
patches to address the problem. The following should already work:

user at .service:
...
[Service]
Environment=XDG_CONFIG_HOME=%h/.config
Environment=SSH_AUTH_SOCKET=%t/ssh_auth_socket

and even %H should now properly expand to $HOSTNAME, I just saw a
patch fly in this week.

I'm thinking that the settings you want to set should be read/executed
when you open a terminal, but there's no need to set MAKEFLAGS for
gnome-session... This is outdated and we should work on fixing this,
instead of giving up and going back to the VW transporter and sniffing
glue ;^)

So, come help trying to resolve these issues with me!
