For optimizations of Os and O3, binutils needs --disable-werror.

-pipe can affect test suites. Multiple jobs may affect test suites,
and some Makefile systems will disable job control for the tests and
even during building if required.

The users that know a lot about optimizations are apt to use them and
will configure their build to use them.
Leaving it up to the user is the best way for an automated build.
