The original wc code had almost no abstraction around the pristines (as far as
I can recall, it's been a long time since I looked at it).  WC-NG has more
abstraction around them than I recall (I just went and looked).  There is a
function that retrieves a stream for a pristine, but it doesn't seem to be used
everywhere.  There are an awful lot of places where it seems we're just passing
around the filename (many of which appear to me to be passing through several
different layers of the libraries).  Someone needs to untangle this mess and
get every use of the pristine using a definitive abstraction that can then be
made to handle missing pristines.  That's not a trivial task.

No there is not.  You delete a pristine the working copy is busted.
