Absolutely.
But I say, there should not be any room for -Werror in production
SW/packages.
The fact,
* different version of gcc raise different warnings
* gcc on different architectures raise different warnings.
* gcc raises warnings on coding styles.
makes -Werror non-suiteable for long-term maintainance.
Worse, this causing non-experienced packagers to take action on
non-issues and potentially introduce bugs.
Most absurd piece of a spec I saw in Fedora spec recently, was this:
...
export CFLAGS="$RPM_OPT_FLAGS -Wall -Werror -Wno-unused-function
-Wno-unused-variable -Wno-unused-but-set-variable -Wno-array-bounds
-fno-strict-aliasing -Wno-logical-not-parentheses
-Wno-error=misleading-indentation"
%configure
...
