ZHA Device Handlers version 2 (ZHA-Quirks V2) architectural design developer discussion

[Hedda]

FYI, just want to raise awareness to any ZHA Device Handler (a.k.a. quirk) developers here that you might be interested in following this architectural proposal and developers discussion about changing how to decouple entities exposed in the ZHA integration from underlying zigpy devices, clusters, and endpoints to make it easier to develop quirks as ZHA Device Handlers. So if interested please see:

zigpy/zigpy#1312

Summary; the discussion includes a new API concept that will allow ZHA-quirks developers to add support for a new device that uses non-standard Zigbee clusters and attributes without having to both create a quirk and modify both the codebase of the ZHA component in the Home Assistant code. The proposed idea was raised now by puddly with a suggestion on how to make quirks easier and less complicated to create and edit by new ZHA-quirks developers.

PS: Also posted info in Home Assistant community forum but still easy to miss for other projects and developers who are not leading ZHA development:
