Straightforward enough, except for the needed belt-and-suspenders sanity checks to avoid foot shooting due to exports not being key/value stores. * Even when annex.verify=false, always verify from exports. * Only get files from exports that use a backend that supports checksum verification. * Never trust exports, even if the user says to, because then `git annex drop` would drop content if the export seemed to contain a copy. This commit was supported by the NSF-funded DataLad project.
