Not sure if this helps you to decide or not, but the current WC
implementation has two different property stores, one for regular versioned
properties (which has both BASE and WORKING), one for wcprops (which has ...
neither, really). The wc-props abstraction isn't strictly required going
forward, but when talking to pre-HTTP-v2 servers, the absence of wc-props
has the potential to vastly slow things down.

(There's a third concept called "entry props", but these find their storage
as fields in the svn_wc_entry_t.)
