I would say: most of all it completely defeats useful text searching.
Any ORM (or anything else) that enforces a primary key integer column
named 'id' is bad technology and should be avoided. Schema should
define the 'object model' not the other way around; I'd estimate that
around 20-30% of my life's work has been cleaning up the various dreck
left around by those who fail to grasp that basic principle.
