It raises a couple of questions though:-

no.

In my first developement version of this plugin, i have started to study
this way, but stopped it to implement a tool to edit pictures one by one.

There is a report in bugzilla to implement something in this way. it's in my
TODO list.



    Is there a way to 'export' Digikam comments to metadata in bulk,

yes.  For comments you can do it to select all picture from an album, open
caption & tags tab on the right side bar and to change what you want here
(caption, date, rating and tags). all metadata from selected pictures will
be modified.
