> (a) one of them licensed their process from the other, like IBM/GloFo/Samsung back in the 2010s or (b) you planned for this in advance and designed a custom "least common denominator" process (like MOSIS SCMOS) to target which means making very large performance sacrifices.

The availability of open design rules improves the feasibility of either approach. Any other foundry implementing a 130nm process will be able to refer to the open rules quite directly, with no strings attached - and they will also have very clear incentives to push in that direction. So no, this is not a full fab process, but it's getting remarkably close compared to what we had before.
