Thanks for the suggestions, support on PlatformIO has been discussed internally and with the PlatformIO team, however, the PlatformIO team couldn’t provide community support as they used to so it will have to be a business contract if any support were to be provided from their side.
Porting to a new platform requires quite a lot of manpower, and it’s not worth it if only a few people would actually need it and even fewer like to contribute, that’s why it’s still under pending as we like to see if there is any community efforts to start off. If there is, we would love to help in any way possible.
