I got greedy and created a new issue and PR. https://hibernate.atlassian.net/browse/HBX-2015
Please let me know if you like the spirit of this change, as I have quite a few in the same vein. I have a shema-first project going on where I have heavily customized the generation output but I had to do really ugly workarounds to get the OverrideRepository to play nice with my custom RevengStrategy implementation.
Thanks for your attention, cheers.
