That has become my acid test for how good an ORM is.

Most fail horribly. I count myself lucky if I come across an ORM in some language that didn't visibly have joins bolted on the side in such a way that they just barely work, usually spending all the design value of the library in the project. (That is, merely by using one of these libraries you've often incurred technical debt on the spot.)

Just out of curiosity, have any passed this test?

Based on reading the documentation, I think Hibernate for Java would qualify. I've never used it, though, so I can't be sure. SQLAlchemy for Python also looks good, but I've also never had the opportunity to use it.

hibernate will make you throw up with all the verbosity and nonsense.

sqlalchemy, on the other hand, is good.

All sufficiently large CRUD apps either use an established ORM or re-invent them poorly.

That's not true, work with some legacy perl apps from the 90s, it's raw SQL all the way down.
