That's a distinction without a difference. Users own processes, and
only one user is logged in to any terminal. who(1) manages to report
who's on what terminal.
If that strikes you as a leap of logic, I can only say it's commonly
$ man -k user | grep -E '^write|^wall'
wall (1) - write a message to users
write (1) - send a message to another user
I grant maybe using the user's environment to express a preference to
another process wasn't the brightest idea. We can both think of better
ways; I offered another. Are you opposed to the notion that the
recipient be able to express a preference for the write(1) message date
format, or are you really convinced it's technically infeasible or
