I am pretty sure that this is not the case. SAT solvers are extremely
efficient and reduction to SAT has replaced many specialised search
algorithms because of its efficiency. Apart from that, one can always
feed complex instances back to the SAT Race, making hundreds of
researchers fine-tune their tools on the specific problem structure...

However, finding minimal unsatisfiable cores (which are basically needed
to get output for the "A might not migrate because of ..." bits) is
harder, especially if they have an even weaker definition as in the
MAX-SAT setting. For that, i would recommend reviewing the current
literature.
