Found a commit that removes one of the most advanced upscalers, LDSR, why did this happen?

[NeiroNext]

I found that the most powerful option, LDSR, disappeared from the list of upscalers. I dug through the commits for a long time and found that there were three commits that completely cut out such a powerful tool. I can't understand why this was done and how to get it back?

Here are the culprits of the problem: https://github.com/lllyasviel/stable-diffusion-webui-forge/commit/471d07caddb423d74fdaa5f04f6f71eb313c65f2 and https://github.com/lllyasviel/stable-diffusion-webui-forge/commit/bccf9fb23a2cbc9d42091a856b3d35b2c4414d51 and more mini fix.

From the commit, all I understood was that perhaps this upscaler was unsafe and closed, but there is little description, so I don’t understand this commit. Can you describe what problems it caused?
