Reason for incompatibility on Original Switch?

I know I'm late to the party, but I got SO excited when I realized PW2 had come out!! I went to buy it and immediately discovered... It's only compatible the Switch 2, not the Switch 1. Did the devs say anything about why they did this? Switch 2 hasn't even been out a year yet! I know it's available on some other platforms, but Switch was my preferred because portability. And there's no way I can dump money on a Switch 2 right now. I guess I'm just disappointed. I'll probably get it on Steam, but my laptop isn't the best. I don't understand why they'd limit it to a new console when it hasn't even been out that long yet.
