Hi Michal, I agree that relying on a vendor-controlled repository would create this risk.
That is why I propose hosting the HAL under the NuttX organization. Both the vendor's code owners and NuttX committers would have review and merge rights. If the vendor stops maintaining the HAL, the NuttX community would still have the source code and authority to continue maintaining the version used by NuttX. This also allows NuttX-specific fixes to be reviewed and merged without depending entirely on the vendor's priorities. I believe this model offers a practical balance between community control and vendor-supported long-term maintenance. Do you think this model could help reduce those risks?
