I'm opposed to adding this particular feature.

When implementing this kind of business rule I'd need the option to specify
a percentage, not just an absolute value.

I would focus on trying to put the data required to make this kind of
determination into a place where applications implementing such business
rules and monitoring can readily get at it. The "ERRORS TO" and maybe a
corresponding "STATS TO" option where a table can be specified for the
system to place the problematic data and stats about the copy itself.
