This is starting to sound like uv is a trojan horse that was introduced as a package manager and is now seeking to replace the diverse python ecosystem with a totalizing approach that is anathema to the the python way (standardize protocols, accommodate diverse implementations).

They've been very outspoken about the intentions of uv being a similar tool to cargo from the start.
