Sometimes you are not solving problem. Sometimes all that you have is backing of VC support and the chain investment done in a random way. That is the story of the venture capitalist supported chains. And hoskinsons continue to get new investors over the year. Now they need the chain partners in order to keep functioning and having any use case. So they are adding the partner chain concept. 

What this partnerchain concept would do? Knowing how Roger ver turned the bitcoin cash into rug pull chain. I have no assurance in my mind that this would be any good chain bridging concept. It would only connect these blockchains with each other. And it would make the partnerchain concept to more developer friendly bridge in near future. Considering hoskinsons has done nothing bigger on the Cardano. We have a lot of things to watch out on such chains you never know how that would hurt the average innocent consumer. 

You can expect the bitcoin cash getting the support for the smart contracts just like how the cardano is doing that with the bitcoin. And it would be interesting to see how the marketplace and the DeFi bridging is going to help in upcoming times as well. Apart from that I feel it's kind of risky chain and it is partnership with other chains sounds risky in the long term.
