That's what I was referring to. I don't use a lot of plugins, but some of them are not "official", so there's no consistent way of having them backed up.
I hope one day we'll be able to have one "backup config" file/archive with all config files of all plugins, official and unofficial, that gets imported easily.
Another annoying thing was having to reformat a usb key with fat32 specifically to reimport the config.xml I had on git. I had it on my Ventoy USB drive, that is exFat, used to reinstall opnsense iso, but it didn't mount it, I had to prepare another one specifically, after trying to understand why it didn't mount it.
Little things, that all summed up make a difference when you're anxiously trying to recover the fw installation.
