Just to clarify, since the automatically generated email from chromestatus might not be 100% clear: The request is to extend the OT to M132 The email says the milestone for extension 1 is M132 and for extension 2 is M129, but it should be the other way around. There was a first "extension" that was not really an extension, but a shift in dates since the OT actually started on M124 (and is scheduled to end in M129). Now we want to extend the OT to M132 to experiment with changes that try to address feedback from the WG.
