Indeed, my bad, I failed to read the critical part :
-o password_stdin
read password from stdin (only for pam_mount!)
(sshfs manpage)

Because I want the repertory readily accessible by non-technical users,

precisely to my use case, i.e. automatic mount at boot/login. I shall
remain with an alias for the mount command and type the password(s).
