I think this is always a problem with any spark job that involves join. If
the join estimations are wrong you get OOM. That doesn't mean that we
completely disable broadcast join for everybody. if your users are unable to
disable broadcast join via config, then maybe you can disable it for them on
your own fork so that it doesn't affect everybody else who is using Iceberg.
