For various reason, we haven’t had any open discussions on the topic: folks are busy mostly in torch-mlir, IREE, XLA, or at Modular.ai. Poking at the people actually involved in this I got the impression that the timing was just right yet to add more meeting on this topic.
The main track I’ve been engaging on recently is [RFC] Restructuring of the MLIR repo as a first step to enable “integrations” to start developing in-tree.
