Yes. We lose those because they are not parsed at all, so we cannot quite
reproduce them. Editing the metadata with LVM that understands the segment type
will restore the fancy comments and formatting (since these are hard-coded in
the export code for any given segment).

See also the testcase: doing a restore/backup cycle will restore the
(formatting-lost) volume group to exactly the same state as before.

Yours,
