Totally
Now with AC you can make just some one make series (Praga R1, Abarth 500 Assetto Corse, Porsche GT3 Cup) and you have a decent rooster just for LMP1, GT2, GT3, GT4
Then we have a plenty of road cars and sparsed race cars without competition or without appropriate tracks to race
For example with the new ferrari DLC we gave the 1967 F1 car that battled against the Lotus we already have but just 2 tracks from the late 60s to race on (3 if we consider the Green Hell Too) frankly a bit few to make a "championship"
I love AC but it would need a more organic approach reducing the number of the "one hit wonder" race cars and filling better the various classes (for example with Lotus they failed to BoP the two racing Evoras info a racing class, they are Too slow for GT3/GT2 and Too fast for GT4, it ends that those two Amazing cars are never used cause they don't fit into any Racing category)
