Me and some others have asked Petar about it in the Ego Engine Modding Discord, he is busy but an update is possibly going to happen sooner or later. No time frame though. You probably won't see too complex mods for a while but give it some time
I recall that this seems to happen most years. Once he has the time to dedicate the flood gates open up.
I think this year my plan is to hold off playing much until modding picks up and we have a solid flow of realistic liveries and track updates. The new tire texture mod is quite stellar, along with a few others, so I think it will be a good winter!
I wish these came out at the onset of a season instead of at the end though, sort of like a Madden NFL or NBA 2K game.
