  Newly-published $^{42}$Si gamma-ray spectra and a final-state-inclusive
$^{42}$Si production cross section value, obtained in a higher-statistics
intermediate-energy two-proton removal experiment from $^{44}$S, are considered
in terms of the final-state-exclusive cross sections computed using proposed
shell-model effective interactions for nuclei near N=28. Specifically, we give
cross section predictions when using the two nucleon amplitudes of the
two-proton overlaps $<^{42}$Si$ (J^\pi)\,|\,^{44}$S$>$ computed using the
newly-proposed {\sc sdpf-mu} shell-model Hamiltonian. We show that these
partial cross sections or their longitudinal momentum distributions should
enable a less-tentative interpretation of the measured gamma-ray spectra and
provide a more quantitative assessment of proposed shell-model Hamiltonians in
this interesting and challenging region of the chart of nuclides.
