The question to seek is WHY are they there?

The "courtesy tones" serve a purpose (yes that is a funny name and I don't
know where it started, but)...to tell when the timer is reset.

Hi Ken -- ignore the nasty replies

I always ignore the crackpots; most have no lives and nothing to say
of value.

Well, NASA uses roger beep with its astronauts and ham repeaters use
them all the time, but call them courtesy tones. So I see no problem
with experimenting on SSB, especially with folks I know who have no
objection. Especially if the tone if not loud or extravagant.
