Quoting Chad on Ie8783e87: «Really, Import should be fixed so it doesn't explode on unrecognized tags :(». And the fix should probably be backported to all previous releases. (I've no idea if we have other import/export backwards compatibility problems.)
It's not a regression, it's always been this way :(
As commented in the change, the Import format was rewritten in 1.17, and I don't think it explodes on unrecognized tags from that version on. As our last supported version is 1.18, I think we can close this bug after adding tests (and verifying they pass).
A parser test is not relevant to this bug.
