What happens if you accept the exact dependency and other packages also have an exact dependency but on a different version, like maybe 0.11.6 or 0.11.4?

Then you get a mess.

Bad enough that some packages require Python 2.7 and can't use Python 3.6 or 3.7.

Does homeassistant really require 0.11.5 specifically?

What is hass?  I thought Hass was a variety of avocado.
