You can do this everywhere. Not just libraries. I take great pleasure in using the old 2022 LTS builds of Unity. The stability of these products is incredible compared to the latest versions. I simply have to ignore console errors in unity 6. In 2022 they are much more meaningful.
Think about how much cumulative human suffering must be experienced to bring you stable and effective products like this. Why hit the reset button right when things start getting good every time?
Even Windows admins often wait a while after the release of an update so they don't get a bad update from Microsoft, which is a real concern unfortunately.
