How to kill the standard PNG loader now that PNG.8bi is no longer a separate plugin in Photoshop CC?

We've been using PNG for saving lossless RGBA textures for years, and due to Photoshop devs preferring the transparency interpretation of the PNG format, we've always used SuperPNG to both save and open PNG files (to recap, that plugin reads PNG transparency as an alpha channel and saves it back like an alpha channel, without killing RGB values of transparent pixels like standard PS PNG implementation does).

To prevent Photoshop from opening every single PNG with it's default plugin, we've always simply renamed or removed PNG.8bi plugin from File Formats folder, allowing SuperPNG to take over. Unfortunately, that seems impossible with Photoshop CC - there is no such plugin anywhere, and consequently, no way to remove standard PNG handling.

How can we solve this? I'd really appreciate any advice. :)
