There is a very long stretch between "should not" and "will not". When the proper means-and-methods are readily available, one *should not* take the lesser path.
Ordinary insulating tapes can be used in the proximity of ordinary
electronics, and it would be misleading to claim otherwise. If the
circuit includes small-signal mosfets with unprotected gates, then I
would consider taking more precautions, but those have been uncommon for
many decades.
