Rather than inventing a new language Perl may be a very good language in 
which to capture site-specific rules.
If we can ensure that CheckCanChangeField has easy access to sufficient 
information and is structured in a manner that causes site-changes not 
to generally conflict with BZ update, this is a perfectly good way to go.

If CheckCanChangeField has the old and desired new field values 
available to it according to a very standard naming convention, and has 
a point in the code resembling.....

#
#
#
# insert site-specific rules CheckCanChangeField here
#
#
#
#

Then it would be very rare that such rules would cause merge conflicts.
