Appropriately treating it like "my networks" and/or RFC1918 in your routing policies (not exporting it, not accepting routes for it, etc.) would be required to properly ensure network stability of course.

Do you think this still holds true if DoD were to (e.g.) sell that space to $CLOUD_PROVIDER or $ISP or $SUPPLIER or…?

I don’t have any knowledge of any events surrounding this space currently, but I do know that press releases and congress have discussed that possibility, so it cannot be ruled out.
