It would be useful, if cargo would assign a gardening category (e.g. "Pages with incorrect cargo queries") to a thusly affected page automatically.
I create cargo queries with templates (I assume, like most people). My data structure has grown quite complex and if I change something in a table definition, that can have repercussions and ripple effects throughout my project. Identifying all affected pages and especially those, which stopped working, is an arduous task. The proposed category would help a lot. :)
