Deleting rows from TR_WEB_SOURCE_NO

Hello! Simply for the purposes of easing navigation of the TR_WEB_SOURCE_NO table within Tessitura's System Table Maintenance window, we're contemplating deleting inactive rows that haven't been updated recently. I imagine best practice is simply to leave the rows inactive and just get over it, but are there any technical reasons why a mass deletion like this would be inadvisable? 

Thanks for your time and advice!
