Awesome, thank you for stating this very clearly. For OpenStack manila,
I've lined up the patches like you've indicated:

Phase-1: Now -> Ussuri-1 milestone (deadline R-22 )
** openstack/manila will drop support for python2.7:
https://review.opendev.org/#/c/691134/

Phase-2: milestone-1 -> milestone-2 ( deadline R-13 )
** Client projects and tempest plugin will drop support for python2.7:
    https://review.opendev.org/#/c/691183/ (openstack/python-manilaclient)
    https://review.opendev.org/#/c/691186/ (openstack/manila-tempest-plugin)
    https://review.opendev.org/#/c/691184/ (openstack/manila-ui)

Phase-3: at milestone-2
** Final audit on Phase-1 and Phase-2 plan and make sure everything is done
without breaking anything.

I'm using the Gerrit topic "drop-py2" to track these.
