The knowledge is there but the information may not be trivially available to make the right decisions. Parts of the BLAS/LAPACK checks use the "check everything" approach. For example

The assumption is that the link will fail unless the correct libraries are in the list. But apparently this is not the case; it returns the first case that links but that case does not run which is why it appears to be producing "silly" results.
If you set the right MPI and threading library, at these locations instead of trying all of them it might resolve the problems.

I agree the MKL + GNU compilers is commonly used and should be tested and maintained in PETSc.

It’s tricky to check directly in the source (we do check in BuildSystem) because there is no such thing as PETSC_PKG_MKL_VERSION_LT, but I guess we can change if defined(PETSC_HAVE_MKL) to if defined(PETSC_HAVE_MKL) && defined(PETSC_HAVE_MKL_SPARSE_OPTIMIZE), I’ll make a MR, thanks for reporting this.
