To show good faith Intel could guarantee that the source will be opened when it can (supplying a date) and release the GOP driver source for platforms that do have released PRMs.

IMO releasing a PRM can't act as a reference point for this. As Intel
decides when and if the release of PRMs happens and that is often more
than a year after a platform launch, the code would be outdated and use-
less by then.

But before entertaining the idea of a later open-sourced blob further,
I want everybody to be aware of the following: Last time a similar
blob interface was merged upstream, it took 11 months to get it through
review[1]. And that was for an optional interface; the blob can do its
primary job without it. So even if by some miracle we would agree on
a blob now, it would still need to be designed, discussed and reviewed.
It's too late for Meteor Lake anyway. So I don't see why the community
should bother with it.
