What do you mean by thing of the past? Are you suggesting keyboard interaction instead?
I think given what the ipad is (a tablet which is meant to be interacted with using touch, I think relying on an external tool as a primary method if input [e.g. To zoom, rotate and pan] would be a little weird). In fact what i think would make the app even better is the ability to use more touch gestures to accomplish some simple tasks such as going backward or forward like it’s done in procreate. That being said, I don’t think that keyboard shortcuts are A bad idea, but I believe that they should be complementary to the app (again using procreate as a reference).
In short the app should be able to perform all the basic tasks without a keyboard, but the keyboard can be used as a tool for shortcut commands [e.g: Boolean, revolve, change views, select a specific tool and so on,…]. I hope other Shapr3D user will agree with me on that one and that the Shapr3D team will add that on their least of upcoming features.
