These issues are easy to miss and overlook. Making them louder helps
Additionally, requiring the users to remember a dozen flags to make the
compiler strict rather than compatible is just terrible UX.
Today, developers need to both care and know about toolchain oddities to
effectively catch these errors, not just to care.

Both the GNU Toolchain and the GNU Toolchain users will benefit from a
People can and have stopped using the GNU Toolchain due to lackluster
and non-strict defaults. This is certainly not positive for the brand,
and I doubt it buys it much good will.
Depending on what exactly you mean by package maintainers, there's
already precedent on how to provide an out (and the OP talks about that
