Nice, I am impressed that you saw some basic patterns have changed.

In the future I am pretty sure we can remove ABEcoinventDownloader completely.

One last change needed (building on LCA-ActivityBrowser#1301): The current code assumes that a database called "biosphere3" is present, but this is an antipattern. Instead, we should set the default biosphere preference to the biosphere database corresponding to the ecoinvent import. So, if we imported ecoinvent 3.9.1, we would end up with two databases: ecoinvent-3.9.1-something and ecoinvent-3.9.1-biosphere. We need to run the following:

import bw2data as bd
bd.preferences['biosphere_database'] = 'ecoinvent-3.9.1-biosphere'
bd.preferences.flush()

Added the bd.preferences to update on eco version page.
Do we need to run UpdateBiosphere?

Do we need to run UpdateBiosphere?

No. In general this isn't a great idea, and should require manual action by the user after the import complete.

I ended having to integrate UpdateBiosphere for the newly versioned database created. Otherwise the end user will go through the flow of trying to import the database, only to get the update the biosphere by using 'File' -> 'Update biosphere...' message, having to go through the wizard twice to get it to work properly.

This versioned database page only gets shown to the end user if that particular database does not exist already.
