There is no specific target when the task is 'totally done', it's an
ongoing activity that will span multiple releases. I plan to have the
initial patchset merged into master in 2.2 cycle, but there's more work
to be done when upstream components currently stuck in python 2 will
finally more to python 3, and fixing up any loose ends, obscure

I think there will not be. There are too many recipes in oe-core that
are python 2 only (and even more outside of oe-core), and it's too much
work to add warning suppressions to them all. Also, we don't want to
force python 3 transition on anyone outside of oe-core, people can do it
at their own pace and schedule.

This is a question for bitbake developers I guess, not me.
