Always and ever, but home partitions tend to have, like mine, hundreds of gigabyte and more. Reinstalling a system takes 90 minutes, but getting the home partition back is a completely other kind of sports.
Why do you want to convert an existing LUKSv1 home partition to LUKSv2?
Well, if you had your system running for more than a few months, getting root partition back with all configuration restored is more effort than just a simple reinstall.
The migration path is still unclear to me. Multiboot systems would also be an issue - what if the disk is shared e.g. between a TW and a Leap installation? Will Leap get the LUKS2 support, too?
Why do you want to migrate a LUKSv1 partition to LUKSv2? And in the case of sharing a home partition between TW and Leap: just keep LUKSv1. Migration makes only sense to me, if you could use afterwards new functionality you urgently need. And most likely you will get this new functionality only with a fresh installation, since the "right" LUKS disk format is not the culprint.
