We use "epoch" it the sense "the start of a new timeline" or "era", because there will be a "before" (python2 eopkg and Solus SC is the default in the package repo we use) and an "after" (python3 eopkg and KDE Discover/Gnome-Software will be the default in the package repo we use, python2 eopkg will not be around and python2 may be removed entirely, depending on the outcome of our internal R&D).
This will be a pretty big deal for the people maintaining the distro. For users, it should ideally be super boring and uneventful, paradoxically enough.
