Lazydocker is made by the same guy yes! I don't find it as useful though.

I usually agree. I spent way too many hours making aliases and I'm very proficient at it. But sometimes there's something like lazygit which does everything my aliases did, but slightly better as it gives me, for example, line-by-line staging and vim keybindings.
It is true that it does not compose, but I can still (and do) use the command line. It's just a nice increase of productivity in 90% of the cases (for me!)
Note: I'm not related to the lazygit project in any way, just very satisfied with it
