Well, this is very unfortunate.  Both url.purge and hash.purge are  
command line only, correct?  Can you think of any way to purge all  
variants via a PURGE request with some vcl tricks?

If not, then are there any plans to support proper variant purging in  
vcl?  I realize this may be difficult problem -- Squid also only  
recently managed to fix variant purging.  But it's a serious problem
