I agree with you on all of these, plus I would like these from the Hanna-Barbera library...
* These Are the Days (1974-75)
* CB Bears (1977)
* Skatebirds (1977) / The Three Robonic Stooges (1978)
* Jana of the Jungle (1978)
* The New Fred and Barney Show (1979)
* Trollkins (1981)
* Jokebook...
Yes, The Flintstones had six seasons.
Seasons 1 and 3 both had 28 episodes, hence 7 episodes per disc on 4 discs.
Season 2 had 32 episodes, so 8 episodes per disc on 4 discs.
Seasons 4 to 6 all had 26 episodes, so 7 episodes per disc on discs 1-2, and 6 episodes per disc on discs 3-4.
I think...
I really enjoyed all the Hanna-Barbera DVDs that were out in 2019...
Paw Paws
Jonny Quest (Blu-Ray)
Wally Gator
Lippy the Lion and Hardy Har-Har
The Jetsons (Blu-Ray)
Therefore, I do hope WAC will continue to put out more new Hanna-Barbera releases on DVD and Blu-Ray this year!

* Touche Turtle and Dum-Dum
* Cattanooga Cats / Motormouse and Autocat
* The Flintstone Comedy Hour (1972-73)
* These Are...
