The reason I was hesitant to store X-GM-LABELS as a header in the
message is because it is mutable, similar to the flags. I could change
labels for a message on the server and I would expect OfflineIMAP to
sync that to my local copy; but it's my understanding that Maildir file
contents are supposed to be immutable.
