After some investigations :
plasma uses le /etc/X11/Xsession script, which sources
/etc/X11/Xsession.d/*

In the sourced snippets is /etc/X11/Xsession.d/90x11-common_ssh-agent

The effect is that if /etc/Xsession.options sets use-ssh-agent, it
starts plasma with the ssh-agent startplasmax11 command. Thus, systemd
is given the SSH_AUTH_SOCK variable (and the sock is at a random place
under /tmp)

Then ssh-agent.service seems to do nothing since ssh-agent is already started

Setting no-use-ssh-agent in /etc/X11/Xsession.option is a no go : it
is also tested by ssh-agent.service

Only solutions I see would imply modifying
/etc/X11/Xsession.d/90x11-common_ssh-agent, but is it a configuration
file ?
