That's a complement :-)

We're not talking about the state of the connection, we're talking about when the
commit occurs. Is it, where my code assumes it is in the example I posted above
or is in the JTA transaction demarcation after the method ends (breaking my code!).

By breaking my code, I mean I start another transaction on the connection
or I do something else that requires the transaction committed succesfully.

This is broken. I'm not going to break other people's code to make this work
(or more likely lead them to make the same mistakes).

It will also lead to non-portable code. Other appservers won't run it.

If you want to introduce a ManagedConnectionFactory property that does

  | setIgnoreAutoCommitInManagedConnection(true);
  | 
then go ahead. But it needs to be false by default and come with a big
health warning about setting it to true.
