Yes, it also broke the GreenDragon bots: https://green.lab.llvm.org/job/llvm.org/view/LLDB/ which you wouldn't be able to update yourself.

It's not, except that maybe one could argue that packaging is maintained by a Python workgroup and has millions of users compared to this packages which seems to be maintained by a single person and has a few thousand users. More importantly though, we should have the same solution across subprojects to avoid bots and developers having to install an increasing number of arbitrary packages.
