Just a impression to see discussion here: I have an experience to have open source PDK project for five years, and found that since semiconductor design has so wide variety of possibility to realize, and the spectrum of the contributor’s interest is also so wide, the points to be weighted should be made clear, since human resource is limited, especially in phase of PDK development. “Semiconductor can realize everything” can be “can’t realize anything. For example, it might be one choice as the first step to focus on only digital PDK with standard (non-HV) I/O.
