Improved manufacturing techniques for these lenses is likely another reason (on top of what is already mentioned in the comments: high resolution sensors and a changing market for such lenses). I have found that I prefer modern Voigtlander lenses with my FF mirrorless body. They're small, but hefty with great build quality and image quality. The CV 15mm f4.5 and 40mm f1.2 are all you need for a fun day of photography!
