Whilst this is dependent on the API version of the Oculus SDK used, it was mentioned somewhere, I do believe, that a new keyboard would be desirable.
However, on the Quest platform, with supported API versions, Quest developers can already use the Keyboard Overlay as part of the system's Focus Awareness to integrate the system keyboard within your app.
If this API is available to you
, it is recommended that it be offered, either optionally or standard, on Oculus platforms, as the primary means of input. This keyboard, in it's full form, is more versatile, adjustable, and functional than the stock VRChat Keyboard, and would provide a more seamless, integrated experience.
The keyboard patches already are a warm welcome; but using the system keyboard may bring additional improvements more rapidly down the road.
