I believe it enterely depends how it's used. But certainly you're right
it can create confusion in terms of backups.

The idea here is that no metadata would need to be preserved except for
backups of the working dir (note: not backups of the archive where the
patchsets are stored, and the archive is the real thing that matters,
the working dir is more a temporary thing, the archive is the real
database).

I'm not actually advocating the multiple channels for metadata in the
kernel, I was mostly making an example of how you could cleanly split
the arch metadata from the data, while at the same time to be still able
to avoid running add-tag etc...

However again, I'm fine that taglines are available too, so I only need
explicit mode to be safer (because explicit obviously it can be
implemented mathematically *safer*) and more transparent than the
tagline. Since I need to use "explicit" for the strict commit, I would
only lose the math safety guarantee by using tagline. I see only
disavantages in tagline vs explicit, if you need strict commit like I
do.
