That makes little sense IMHO -- the systemd user instance needs to be able to
see ~/.config/systemd/user/ at startup, and on logout all user processes
including systemd need to stop before you will be able to unmount the
unencrypted $HOME -- so the mount/unmount needs to be done by a PAM module
(pam_ecryptfs). This works just fine in Ubuntu at least (I've used ecryptfs on
my $HOME for many years).

So a user systemd unit for handling ecryptfs mounting seems both unnecessary
(it was never needed in Ubuntu, for example) and actively harmful as it's the
wrong way around IMHO.
