Shipping of Compute Pressure API has been changed from M124 to M125. Today is M124 branching and we are not fulfilling all the requirements for shipping given the ongoing discussions, the filed issue <https://github.com/w3c/compute-pressure/issues/253>, and one missing LGTM. We are still actively working on the items just mentioned to see Compute Pressure API shipping in M125.
