The GSI is based on Andy Yan work. Modifications are minimal and will be published a bit later. Maintenance will be easy, as long as the original work continues; and the GSI will thus receive regular updates. The impact on regular devices production will be negligible.
We don’t actually intend to give a lot of support to the GSI, nor make original development on it. This can more be viewed as a gift to the community, and support can be found in many places (including here, thanks to active users). Of course, we hope to attract a little bit more attention, and maybe gain new users on regular devices.
This is for the starting point, nothing being set in stone.
