> Anyone would think it to be ridiculous if a carpenter told you he only works with saws because he is a saw carpenter and that for other kinds of work you should see the plane or sander carpenter.

...and yet there are specialties within like "framer" and "finisher", among others. Then you have interior workers like specialized custom cabinet makers, flooring specialist, drywallers, painters, etc.

What I'm trying to say here is that even in "carpentry" for putting up a house, there are numerous specialties.
