IoT Hub device and module twins limit.
There is limit of 8KB limit for IoT Hub device twins. What’s the limit on module twins? How much total size allowed for both device twins and module twins? Is any plan to enhance the size of both twins in GA or later release?
IoT Edge now matches the increased IoT Hub limits:
– Device and module twin size increase from 8kb to 32kb
– Increase levels of nesting in a device and module twin from 5 levels to 10 levels
– Increase size of key/value properties: key size from 64b to 1k, value size from 512b to 4k
These changes are included in the 184.108.40.206 release that was published this past Monday.

Are there any updates on this issue? Also, what are the reasons this is currently restricted?

I would like to add that I have found the 8KB limit quite limiting. I'm working on a project where a significant amount of customization through deployment createOptions is necessary. We have just hit the size limit and are now stuck. We are trying to find workarounds but in doing so are certainly straying from best practices to stay under the 8KB limit. Even just a 16-32KB increase would be enough to make it so things "just work" as they should, without needing to hack together an unnatural solution.
