I don't know if it's different now in modern systems using Terminfo, but
in older systems $TERMINFO could only be a pathname to a (compiled)
terminfo(5) file.  Mostly this was probably because of the restricted
size of the process environment variables on older systems.

Ultimately I think it's still the user's responsibility to get the
appropriate TERMCAP/Terminfo definition onto the target host(s) in a
secure fashion, and then the existing "convenience" hooks in tools like
SSH will set the right hints about the name of the terminal type via
