I also follow that and it's been that way pretty much everywhere
I have worked, at least recently.

But not literally like that.

Of course, you control which warnings are in effect, and fix those.

You disable silly warnings you disagree with, rather than fix them.

The business of deciding what diagnostics are going to be used and which
are not is a separate activity. Usually most of the activity in this are
occurs when there is a compiler change, such as an upgrade.

The newer or different compiler offser some diagnostics which trigger in
the code, and for each, the squelch-or-fix decision has to be made.

It's not always an easy decision, because the value, or lack thereof, of
a diagnostic is not always apaprent from one situation in which it goes
off. Some diagnostics can be wortwhile in spite of a significant false
positive rate.
