"set termoption" would only work if the current terminal supported
"mono" as a terminal-specific feature.  "set mono" works for all
terminals regardless of whether or not they ever supported a "mono"
keyword in earlier gnuplot versions.

And even for those terminals that [used to] have a "mono" keyword
option, triggering it via "set termoption" would not work in version 5
because the whole system of dot/dash support was fundamentally revised.
The fact that "set term foo mono" wasn't working is exactly what people
have been complaining about, and is the primary reason for the new
approach.  I had not anticipated this would be such a big deal, but
apparently it is.
