Is SoftRAID XT dead?

Is SoftRAID XT a dead product going forward with macOS Sonoma?

I upgraded to Sonoma on my M1 Mac Mini (running SoftRAID 7 XT), and am now getting the license expired warnings. I'm super confused about the upgrade options, because it seems that when I enter my XT license key into the upgrade page, the only option is to upgrade to SoftRAID Pro for $179. When I looked at the store for the current pricing for SoftRAID XT, I see that the pricing for new users is $119.99 (which would imply to me that upgraded licenses for existing XT license users would be less than that), but I also noticed that it only says that it "Now supports MacOS Ventura", and not "Now supports MacOS Sonoma", like the store pages for SR Pro and SR Lite do.

While I totally understand and agree with the need for developers to offer paid upgrades to products, having to pay $179.99 to upgrade an XT license to a Pro license with no other option seems a bit punitive to me, because the main reason why I purchased the cheaper XT license in the first place is because I didnt need all of the features of a Pro license to begin with!

I hope I'm mistaken that XT is a "dead" product, and that there will be a Sonoma-ready version of XT that XT users can upgrade to for a more reasonable upgrade price?
