I don't think there were any 012 Chinese copies when Dorsey's article appeared.
IMO the 012 circuit nicely complements the capsule. The Dorsey variant of the Schoeps circuit was suggested for LD mics, which can be okay with a 35V bias, the capsule giving a higher output than a SD mic. The "Dorsey circuit" was meant to do away with the not so great transformers in most Chinese mics, and, being a beginners' project, it had to be very simple. So he left out a DC converter and all the RF protection. He also put in a hefty (and somewhat rare) 4.7u/50V tanalum cap to filter the capsule bias when he could have used a small film cap in a hi ohms filter network. Or even better two filter stages in series. But that would have complicated the schematic. So keep in mind that the "Dorsey circuit" is optimized for simplicity, not for best performance.
The "Dorsey circuit" is not a good circuit for a SD mic as S/N is likely not satisfactory. The 012 circuit consumes less current and thus leaves about 42V for capsule bias, which is sufficient, the capsule being on the large side of SD.
Most capsules are constructed for 60V. And in those designs, a 60V bias does not change the sound very much compared to lower voltages. A K67 for instance collapses at 120V. You obviously need a voltage well below that so the diaphragm can move with enough amplitude to cope with high SPLs. 60V was found to be optimal. If you choose a voltage high enough to seriously alter the diaphragm tension and thus the sound, you're probably too close to the collapsing voltage.
