You’re welcome – and no, I didn’t take your first statement as grumpy. It was me who made the mistake here because in a first step I did add them back and added this annotation to clear things up (whether they’ve been deleted accidentally or on ground truth was unclear to me)

See https://wiki.openstreetmap.org/wiki/Lifecycle_prefix for further information about lifecycle prefixes. I always do so on dismantled power lines (the middle voltage lines are disappearing quickly here in Germany) to avoid them being re-copied from Bing as long as they’re visible there.
