Openhab-config vs raspi config: expand filesystem

I had saved an 8Gb diskimage of a complete openhabian setup and then wrote that to a 16Gb SD card.
That ofcourse all worked well, but it is only seen as an 8Gb SD card now.
Raspi-config has an option to expand the file system, sadly openhab-config has not. I had the impression previous openhab-config tools had it as well.

For a moment I thought maybe it moved to the ‘basic setup’ option, but did not recognize it at all in the description there.

All in all not a huge problem because I can just ‘apt-get install raspi-config’ and use that, but i was wondering if there is any specific reason why it is taken out, or is it maybe hidden in some option I have not found yet?
