Usually configure flags get saved and reused by examples - and in some cases might be required by applications.
[for ex: if there is -m32 flag (gcc) somewhere. Other example: /MD for MS compiler]
So your "objection" appears to be not based on real requirements.
And for your desired use case: "I need to specify flags to PETSc build - and they should not bleed to dependent pkgs" I've indicated one mode for this.
i.e - do not specify them with configure - only list them with make.
./configure
make CFLAGS='only-for-petsc-library-build'
