Yep this topic was discussed on https://github.com/w3c/mediacapture-record/pull/216#discussion_r1159521616 and earlier. In the end I backed out of my proposed semantics due to scepticism so the PR leaves it unspecified.
During the interim that hbos@ speaks to where the PR was merged, it was decided that a separate spec issue be filed on that topic, https://github.com/w3c/mediacapture-record/issues/219.
