Given all this magic with .with_polymorphic(), I'm now wondering if
it's really worth to have a new Query class (by subclassing orm.Query)
per mapped object just to apply some filters...
At first I found quite elegant to have one Query object per mapped
class, but now I'm wondering if it's

Hello list
I have a simple mapping between a class and a table. What I'd like to
