We can add two lintian WARNINGs:
W: linkage-against-specific-blas-lapack-implementation
triggered when detected any specific BLAS/LAPACK implementation
in shlibs:Depends . The package should link against the standard
blas/lapack:
libblas3 | libblas.so.3,
liblapack3 | liblapack.so.3,
In order to enable the update-alternative mechanism.
W: linkage-against-libcblas
triggered when libcblas.so.* has been found in shlibs:Depends.
that indicates the maintainer may have fallen into a trap.
I'll raise a discussion about this on -science and take further
action according to the result.
