Hello Janina, >From a process perspective, my understanding is that we cannot satisfy that request at this stage of our process: the proposed addition has impact on the conformance (given its "SHOULD" statement), and conformance-impacting changes cannot be included via the Proposed Edited Recommendation process. The Working Group has already started looking at the requirements for a new version of the spec, where these additions could be considered; I would personally support them. But I don't see how we could integrate them in the second edition of the Vibration API within the constraints of the W3C process. Would that be an acceptable way forward for the APA WG?
