symbols have L=0.15 by default but PDK indicates values greater than 0.15.
It is better this is fixed, which channel looks after this open_pdks ? is the area maintainer to check/validate it is more correct to update.
I assume the default is a guide to the minimums to help designer.
I check PDK documentation against each value and the minimum L values follow the 4 pin models.
