Yes, the foomatic-filters package is now discontinued and cups-filters
takes its role now with the new included foomatic-rip filter.

The foomatic-filters package contains also beh but my feeling was all
the time that no one uses it, especially it does not work with filters
which have to run as root, as itself does not run as root. Perhaps it
works if one would set beh's permissions to run as root, but then it
also runs filters as root which should not run as root. Or one lets beh
run as root, but check the filter which it calls and run it unprivileged
if its permissions tell it should not run as root. Patches welcome.

It is also written in Perl, but nothing else in the printing stack is
written in Perl. It should perhaps be rewritten in C or shell. Also here
patches welcome.

Your pipe filter is a good idea, but I see a little missing feature. All
CUPS filters/backends get the IPP attributes/options via the 5th command
line argument. There is no way in pipe to make use of these, so that you
can control the command line being called by pipe by supplying options
to your print job.

Also no program which is not explicitly written for the use with pipe
uses the PIPE_BACKEND_ARGV[0-6] environment variables, and if you write
a program especially for being called with pipe you can directly write a
CUPS backend.

Also programs called by pipe run as lp if pipe is installed world-
executable and run as root if pipe is installed root-only-executable. So
one installed pipe cannot serve both use cases on the same machine.

Bug description:
  Drastic changes in CUPS 1.6.1 (non Apple feature removed mostly) are
  detrimental to Ubuntu users. We should wait until the missing features
  (like automatic appearing of remote CUPS queues) before to unleash the
  newer version to users. This means downgrading cups in Quantal.

  See LP Bug 1061063 and Bug 1052897 for examples and the big list on
  Suse bugzilla : https://bugzilla.novell.com/show_bug.cgi?id=735404 for
