Very true.  And that's a major problem with darcs.

Unfortunately, there's no easy way to solve that.  The representation
that darcs uses for any given patch may very over time: when you push
from one repository to another, the representation for the patch may
change (that's what ``commuting'' is about).  While there is a
canonical form for a patch, it's not at all easy to compute.
