Thanks for your feedback. We will include them in the next major update.

By the way, I would appreciate it if you could assist me in adding some test cases for them.

• apt (specifically for Ubuntu) and apk (Alpine) support direct proxy functionality.

• For the GitHub mirror, the use of the "dumb HTTP" protocol has been disabled, and we need take some time to investigate how to implement proxy.

I believe the priority of these requirements is relatively low.

If you have a need, you can modify the code yourself since the current architecture is scalable.
