It has been a research effort to even provide the properties
that I've reported. I'm not likely to be able to give you
simple or complete answers to the complicated context --and
I most definitely do not know your overall context or
constraints.

If FreeBSD can boot read-only media to some degree, which
it can as I understand, the read-only boot pool might fit
in that category for all I know. I've no clue how useful
such would be to you.

If you have no way to identify and fix potential corruptions,
I'd expect you would initialize a new boot-pool, avoiding
sources of potentially corrupt data. But I've no clue if you
have snapshots, checkpoints, or other such for comparisons or
if it would be reasonable for to you to back up in time if
you do have some known-at-the-time good data, even if now old.

Good luck --or at least better luck than landing in the
disasterous-openzfs-import time frame in the first place.
