Milan Crha created an issue #414:
There's a finishing GSoC work called evolution-etesync, which is currently developed by a participant Nour in his own repository: https://gitlab.gnome.org/nourmat/evolution-etesync/
We, me and Tom (an EteSync mentor), would like to make the module official, thus move it under GNOME. I'd say it can be just created and Nour will move the code accordingly. There's no need to preserve the tickets, from my point of view, because they were highly related to our (code) review process within the GSoC tasks.
