I use them to add customer charter credit vouchers to my Oyster balance
and buy through tickets to places like Bracknell. Both could be done at

Through tickets onto the mainline could be done a different way by
allowing a LUL ticket to be "traded in" against a through ticket at a
railway ticket office instead. I expect they are very much a minority
product, though, judging by how few people seem to put a magnetic
anything through barriers these days on LUL.
