IMHO that's not an acceptable solution. emacsclient should just work in
the default configuration, without requiring the user to jump through
hoops, and an Emacs daemon should persist between sessions (otherwise
"daemon" would be a misnomer). Or is that use case really so uncommon?

Also, if there is a security problem, how would it disappear by moving
the socket to XDG_RUNTIME_DIR? Note that other tools like "screen" also
place their sockets in a subdir of /tmp.
