I am not sure what to think of this PR if you don't provide any motivation.
As all tests fail as well, so apparently more work is needed to get a merge.

FWIW, if that is to remove duplication from specifications here and within setup.py, then you could use the same trick as we and other projects do having smth (leaving with the comments etc):

# Theoretically we don't want -e here but ATM pip would puke if just .[full] is provided
# TODO -- figure it out and/or complain to pip folks
# -e .[full]

# this one should work but would copy entire . tree  so should be ran on a clean copy
.[full]

full here is one of our requires "flavors", so either remove or adjust accordingly ;)

I am closing this PR as there was no reply in 3 months. If @yarikoptic sees value though, please let me know and we figure something out.

that is ok with me -- no immediate need/desires ;)
