I think when it comes to the Habari, it is hard to tell what happened... if the rumored health issues are due to the individual cats in that program or whether some sort of genetic weakness caused by the number of wild cats used in the program reportedly. Given the secrecy of the program, it is impossible for us on the outside to know.
There had been some concern in TICA when Savannah programs used Bengal as there was fear that using two wild cats with the domestic could cause MORE issues with more potential mismatching of DNA. We didn't see that, and TICA eventually accepted that what was important was the Serval heritage and that drama blew over. But I suspect the reason we didn't see issues might be because the Bengals used in SV program were not early generation but SBTs.
There was also the Wagati cat that was very cool-looking, where an F1 Savannah was crossed to an ALC... not too many kittens and I don't think has been repeated since Nicole quit breeding.
