logilab-packaging #299172 renaming the python package from "logilab.packaging" to "lgp" breaks apycot [deprecated]

since apycot (bot-side) does provide an python module named "lgp" (in _checkers/apycot/)... and it's quite painful to change this later (from checkers.apycot import lgp appears in many recipes)
