Basically it’s what I do but I drop an edit note to the recording merge editor because their edits might fail (or mine, it depends which one applies first).
I generally drop an edit note to other editors working on the same entities at the same time, so to let know the simultaneity of editing efforts and to possibly prevent further conflicts. It usually results in cross-votes and/or comments. Here, whether the editor cancels recordings merges or not does not impact the final output, thus there is no conflict (although recordings merges would fail), only duplicated editing efforts.
If it’s going to be an issue, I usually leave myself a note via tags and do it later.
But I can see from your tag list that you already do that sometimes/a lot
