Ard: Now, there is no compatible way to introduce new library class for the basic module. One possible solution is to define the default library instance in package dec file together with the library class declaration.
Beebe: This patch set looks good. But, the last patch 9/9 will require every platform to be updated. I may suggest to merge the first 8 patches for this stable tag 202308. The last one 9/9 can be merged for next stable tag 202311. Then, the platform owner have time to update their DSC first.
