Making the wc spec a document instead of just in the implementation would be a
good thing.
However, TortoiseSVN and all the other apps that use the C libsvn_wc API would
have to use bind to Python instead? Or the Subversion team would write
libsvn_wc in Python and somebody else would end up writing a C libsvn_wc,
because somebody is going to do it because it is needed. I would rather see us
do the C version and other people do the non-C versions.
