Just got a snail-mail from the state of California DMV that they are ending the program because of the new law. The rule changes (quoted from the letter) are as follows:
1) Only a vehicle that is connected to an electronic charging station may park in a ZEV designated parking space
2) A ZEV Parking Decal is no longer required to park in a ZEV designated parking space
3) If the vehicle is not connected for electric charging purposes, the vehicle may be subject to tow/impound
So, it looks like my little square decal will be a collector's item
