Now that many modern diesel locos also spew smoke, there should be "equal time" for showing them in action. Also, now that there are scented smoke fluids available, several smoke options are available for locos whether wood-burning, coal-burning, or oil-burning locos. I have "coffee scented" smoke fluid for use with STELLA'S DINER!
Some local train clubs that sponsor train shows suspend smoking locos as a consideration for young visitors who have have asthma or breathing-related medical problems. Following that practice, I don't put smoke fluid in any of the locos on my home layout for the sake of others.
However, there is a pre-existing "blank" ceiling vent in the Train Room. I intend to install an exhaust fan there so I can "have my smoke and expel it too."
