[Koha] Purging patron records

[Cab Vinton]

Many libraries purge their patron records on a regular basis so that
records don't exist for folks who've died, moved out of town, etc.

My question is whether deleting a patron's record affects any
circulation statistics attached to that record, so that future reports
based on those stats could become inaccurate.

If so, would it make sense to have the ability to "Withdraw" a patron,
in the same way that items can be withdrawn instead of deleted?
