The generic SCSI interface bridges the gap between user applications and specific devices. But rather than bloating a lot of programs with similar sets of low-level functions, it would be more desirable to have a shared library with a generalized set of low-level functions for a particular purpose. The main goal should be to have independent layers of interfaces. A good design would separate an application into low-level and hardware independent routines. The low-level routines could be put into a shared library and made available for all applications. Here, standardized interfaces should be followed as much as possible before making new ones.
By now you should know more than I do about the Linux generic SCSI interface. So you can start developing powerful applications for the benefit of the global Linux community now...
