Before this turns into another 'thread from hell', let me clarify that.
I'm suggesting:
1) remove any remaining knowledge of the magic 'c' partition in utilities
2) remove any assumptions that the 'c' partition even exists
3) stop creating the 'c' partition on new disklabels

This will not break existing disklabels and wont break existing systems
that have the 'c' partition in use etc.  I'm suggesting just completing
the de-magicification of it.  That is, assuming it isn't already done.

eg: things like this:

peter at overcee[12:12pm]/home/src/tools/regression/usr.bin/make-100# bsdlabel da0s1
# /dev/da0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:   262144        0    4.2BSD     1024  8192    16 
  b:  2097152   262144      swap                    
  c: 35840952        0    unused        0     0         # "raw" part, don't edit
  e:  4194304  2359296    4.2BSD     1024  8192    16 
  f:   409600  6553600    4.2BSD     1024  8192    16 
  g:   262144  6963200    4.2BSD     1024  8192    16 
  h: 28615608  7225344    4.2BSD     1024  8192    16 

.. get rid of the "don't edit" part.  Make it Just Another Partition.

Cheers,
-Peter
