Yes, I tried a few things to see if they were written to the image
metadata, and they were.  However the configuration options are not
very clear in how they work which is really why I asked the question.
I don't want to suddenly find I've lost a load of metadata.

Maybe, however it does look very like a check box that has got
squashed and almost disappears for some reason.  The tick boxes all
look perfectly sensible but the odd things alongside "Write this
information to the Metadata" worry me.

Even odder, I just made the configuration settings window bigger and
now there are *three* of the blue dot and white oblong graphics
alongside the text!

I'm not aiming to use these options either.  There's a bit that
worries me *there* though, in the same box as the Read/Write sidecar
files tick boxes is a box saying "Update file timestamp when files are
modified", does this only apply to sidecar files or does it apply to
writing metadata to the image files?
