Hi!
Creating a second backend that uses the same code base will create a
maintenance nightmare. Every change/bugfix that in the future will ever
be done to one of them must be ported to and tested with the other one,
which will create an extra workload for the maintainers of both
backends.
The work needed to merge the new functionality into the existing
backend, though it might look to be much initially, will most likely be
less than the sum of the extra work needed for the future maintenance
for keeping the two backends consistent in the future.

That work can be done, but what about testing? I don't think
we have every single Epson scanner. If at one point SANE switches
to this backend, there's the risk of being overwhelmed by bug
reports about scanners that were working just fine...
Anyway, I'll post a patch in a few days so that others
might evaluate it.
