Well, maybe not quite. ;-)

In fact the normal parted front-end will not resize any partition if it
can't "open" the filesystem.  I'm not sure quite what this involves but
this operation is not supported for NTFS.

I realise now that d-i is using an entirely different front-end which I
will need to look at.
