Yes, F1 2020 is still very good game and provides much fun. I also return to it from time to time or even to F1 2019, if I want to go for some Hockenheim-Action 😀
For the modding, it's true that there are less mods, but luckily the mods we need are still there. There will be enough to have some good myteam seasons. And for myteam I use my Personal Team I keep to Patch into games since 1996. So that doesn't hurt me that much. You have a point, the decline in mods shows the declining interest in the series. There are surely several reasons, but recurring or not fixing major Bugs and ignoring the wishes from the customers takes its toll.
Luckily we can always go for the old games (except pre F1 2012, due to the dead activation mechannism)
