Does even that open a possibility for data loss?

Use of the alternates feature will, to my knowledge, never write the
referenced repository: all new objects are held in the referencers.
The only condition as I understand it is not to generate garbage in
the reference repository, and that nominally does not happen in a repo
that exists only to be an object pool (you probably even want to use a
"bare" repository instead of one with checked out files).

I believe this feature is popular with hosting serving many repos of
the same project.

The especially paranoid may want to try setting their alternate,
referenced repository to be read-only with respect to the user doing
all the potentially-modifying work, undoing this if and when they feel
like adding more objects to the referenced repository. My guess is one
can do a clean checkout and then ride this strategy for quite a long
time (a year? more? it depends on how space-conscious one is), so that
would not be a incredibly onerous paranoia, if one has it.
