With the introduction of the new system preference, TrapHoldsOnOrder, if a library sets this to "Don't Trap", they also would probably not want to get an alert to transfer the items. As libraries are continuing to quarantine their books, they are generally keeping them in the one library until the quarantine is over. However, clicking ignore with each transfer / hold slip for this workflow is a bit much. It would be nice to allow for a library to turn this off - as Koha is allowing with this other system preference.
