I have backups - and the install worked fine.
/home is where many of my documents etc live and I’d restore from a backup anyways to get them back. Sounds to me like it would be a null operation if I wiped it and restored a backup.
This is also me finally performing a reinstall after having problems mentioned in another thread. I’ve been hobbling along on an older version of Manjaro. The good news is, reinstalling and upgrading worked without breaking KDE. It will take a bit of time to get everything back to how I want it, but I’m happy to be free of the issues I was having when I tried to upgrade.
