You can do this already on Android to some extent. I zap in Primal from my node. The big honking ⚡ icon in the middle of the wallet is worthless though, since I cant utilize it.
That said, being able to use the wallet you are already using in another application such as Olas for example is powerful for new users. If I onboard a musician to Primal and Fountain, they have to have two complexly separate walkers. Now imagine them having just one. It's much less confusing.
