Yes, "set termoption" only works for the current terminal.  It is not a 
global setting.

I don't see what the problem is with asking the user to change their 
settings to "noenhanced".  (What if they want enhanced?)  There might be 
another approach.  Try

gnuplot> set term push
    pushed terminal qt 0 font "Sans,9"
gnuplot> set termoption noenhanced
gnuplot> show term

    terminal type is qt 0 noenhanced font "Sans,9"

gnuplot> set term pop
    restored terminal is qt 0 font "Sans,9"
