I think much depends on the type of job we are talking about.
If I was adding a few outlets in someones home I can't see telling the customer they need a Carpenter to come in and cut the openings.
However when I work a new or extensive remodel job that already has the other trades working there I do as little 'non-electric' work as possible.
At the same time I do not expect the tin knockers to wire their fans or the carpenters screw my boxes to the studs.
